This is going to be a short post, but I felt compelled to do it this very moment because I’m getting lots of questions about it. You may have noticed that I don’t recommend blanching your cannabis in any of my recipes or oil tutorials.

Some chefs recommend blanching your cannabis before cooking with it and say it’s the bees knees, but I’ve gotten lots of comments from you guys about how it’s more like being stung by 1,123,314 hornets, leaving you with soggy half burnt weed and weird textured oils.

So what’s up with this technique? And why don’t I talk about it in my recipes or oil tutorials?

Why Blanched Cannabis Isn’t My Thing

There are edibles chefs that argue that for flavor’s sake, you need to blanche your cannabis before infusing oil with it to remove all of the “impurities” found in cannabis. Otherwise those impurities will make your infused foods taste terrible. And that’s really the only argument I’ve ever heard for blanching. They claim that the blanching process will remove all of those nasty little things, make your weed food taste better and give you a more pure cannabis infused oil.

Let’s get very clear about this. When chefs talk about the reason for soaking and blanching, the “impurities” they mention include things like “insecticides” and “chlorophyll.”

I’ll touch base in just a moment why labeling chlorophyll an impurity is ridiculous, but what I’d love to drive home about this topic is that whenever possible, let’s all use cannabis that is grown without using chemical pesticides and fungicides. Especially if you’re using it to treat a condition.

Blanching and Chemical Residues

I’d love to dive into the topic of all of the different pesticides and fungicides that are currently being used while growing cannabis, but I don’t have the time to do that here today. What I will say is that the chemicals used on cannabis are typically much more dubious than those used while growing conventional food.

If you’re consuming black market cannabis, you may be ingesting chemicals that are not legal for human consumption. Many of these chemicals are supposed to only be used in low concentrations on ornamental plants (like the sad shrubs growing in medians and in bank parking lots) and are being used in high concentrations on a plant you put into your lungs and your poor digestive system.

Buy weed without chemicals. Grow weed without chemicals. However you get your cannabis, try your damnedest to buy or grow it sans gnar.

If you do have to buy cannabis without knowing what’s on it, then by all means try to do something about it… these non-scientists say that soaking it in water for a few days and then blanching it will remove all of that, so I guess?… go for it?

I’m not convinced that it removes pesticides from the plant material entirely, and have never been presented with evidence to back up these claims, but I feel like it’s something worth researching.

Chlorophyll is Gross… wait… what?

So now we’re onto that supposed infusion ruiner – chlorophyll.

It’s what makes infused oil green and apparently (according to some chefs) makes your food taste bad. I get that I have a health-based palate (I’d drink Multigreen Kombucha over Dr. Pepper every. single. time.), but I think that there are many cases where infused oil enhances the flavor of what I’m eating.

I think I made one smoothie that tasted a little odd (pears and cannabis aren’t bffs), but I mess up the flavor of my smoothie about 3 times a week, so that’s really not all that special.

IMHO, nearly everything I’ve ever made with cannabis tasted great when I added my infused coconut oil. I put it on toast. I put it in my tea. I like the flavor of cannabis infused coconut oil. Scratch that. I love that flavor.

And here’s what’s crazy to me about this idea… chlorophyl is AMAZING for you. That green stuff that these flavor purist cannabis chefs are saying is the scourge of cannabis is considered a superfood. It is reportedly a cancer-fighting, liver detoxing, wound healing, colon cleansing badass.

And I don’t know about you, but taking all of the trouble of blanching to get rid of something that is good for me? Nah. I’ll pass.

Again, if you hate the flavor of cannabis, really want to put cannabis on fish or in delicate pastries, or if the cannabis you’re using is covered in chemicals, then… why not give it a shot? Otherwise… if you’re using tasty organic homegrown or dispensary cannabis, IMHO it’s unnecessary and can potentially make your next batch of oil more complicated then it needs to be.

I feel like this is going to be one of those troll bait posts that I’m going to wish I never wrote. Let’s do it… in the comments section below 😉

Much love,

  1. I’ve heard (and wondered) about soaking in water to get rid of the “green”. Thanks for clarifying the not-need!

    As for insecticides…I guess it’s “buyer beware”…I doubt that a water soak would remove any chemicals. Possibly a weak vinegar soak??? Luckily, this isn’t an issue for me.

  2. I would have to agree with you Corinne . I love the flavor of cannabis ! I did try blanching a batch of La Confidential, ( which has a strong flavor ) …. it was more of a pain in the @ss ! I say …. to each their own ! Happy Baking ~

  3. Oh my goodness I could not AGREE with you more!! You hit the nail right on the head on every point!! As 100% soil grown organic no pesticide growers and caregivers in the state of Maine I never even heard of blanching your cannabis before using it!! They always think they are on the next best thing, where did simple thinking with your God given brain go to?? And how stupid the logic behind the pesticide water soak and chlorophyll being bad for you?? Well thank God you are using your brains and see the nonsense in this. Thanks for the great article!!

  4. Ha. Wish I were there to high five you. Bad mood or no, it’s real and cuts to the points perfectly! I was curious about it and was on my list to further research but having read this I’m already uninterested 🙂

  5. Yes yes yes yes yes! We grow our own and I don’t worry about blanching for a single second. My edibles are awesome – so I know I’m doing the right thing! 🙂 Sending you and your grumpy a** a big old hug. xo

  6. For some reason, people always think they can improve on Mother Nature and so manipulate stuff for whatever reason…that’s how animals go extinct (e.g. passenger pigeon – squab anyone? Rhino horn, etc.). Bad mood or no, you are right on and I appreciate you said it loud! Don’t mess with a good thing.

    1. Merideth,

      Is smoking cannabis not improving upon it? It seems Mother Nature provided THC-A , yet this blog goes into all the ways to cook with cannabis (i.e. converting THC-A into the THC that gets you high.)

      So please only consume cannabis raw if you don’t want to mess with a good thing.

      Conflating extinct species with blanching weed is folly.

  7. A water soak and blanching makes sense with ABV if you’re using it, really takes out the burnt flavor, but that’s the only time it always makes sense. I’m with you on chlorophyll!

  8. Flavor like most things is a personal issue. While looking for the most potent method of preparing cannabutter. I came across a High Times lab tested recipe. This recipe calls for 1 hr of decarb in the oven, then cool and spray with Everclear before transferring to crock pot. Definitely improves potency but also has the side effect of taming the what I call “green” or “grassy” flavor of previous batches. P.S. I didn’t have Everclear handy so I used the Jose Cuervo Gold I did have. It turned out great. I served the cookies I made with Lime and Salt. 🙂

    1. I just saw this a few days ago and was intrigued. Thank you for sharing your experience with that method. That cookie recipe sounds amazing! This is something I can really get behind. I can’t wait to try it!

      Much love,

    2. Hi Darrell! Thanks for checking out the “Ultimate Cannabutter” videos. Tamar’s decarb + Everclear + Crockpot method is definitely my go-to way of making potent cannabutter, but it does taste grassy! There’s two schools of thought on cannabis flavor, and many chefs seek to eliminate it as much as possible; while others choose to work with it. That’s the great thing about cooking with cannabis, there’s so many variables that it’s possible to tailor recipes to the tastes and needs of individuals.

  9. Couldn’t agree more about chlorophyll. I’ve never understood the problem with it. Maybe because it messes with the flavors of concentrated oils? I make a fresh harvest infused oil with olive oil and it smells and tastes sooooo good it’s almost sinful.

    Thanks Corinne. To blanche the terpenes out of the plant material is concerning too, since no the terpenes direct the action of the cannabinoids. I want all the flavor of the strain I worked so hard to bring to harvest.

  10. I’ve never heard of blanching. From your description it sounds like a crock of shit. I guess if you don’t like the taste of good home grown or dispensary bud, go with the canna caps and just eat plain brownies. : }

  11. Right on !! I saw this method with a product I just bought and said “Whaaaat ?” to myself !!Now I have to do what ??THANK YOU
    THANK YOU THANK YOU !!! for clearing this up ,( I skipped it anyways ) LOL !!!! Love you Corrine ,Feel better !!!

    Yes Maam Your absolutely right. They can tell me the same and I feel the same as You do. And I HAVE BEEN VOTED BEST EDIBLE @slocup2017 and 2nd Place @ harvestfest2016. I have 2 Trophys to say Hey We doing Our thang…

  13. As a baker, I have tried different methods of infusing oils/butter. Recently, I tried the blanching method and I got excellent reviews. There are some folks who really don’t like the chlorophyll taste. High Times tested the potency and the blanching method scored nearly as high as the alcohol spray method. Taste and potency are important to my clientele. To me, it’s just another way to bake.

  14. I couldn’t agree more. In fact, I was more than a tad dismayed when the 2nd Levo infusion guide they emailed me a link to (pre-product arrival) actually flat-out RECOMMENDED blanching cannabis before infusing with it!! My immediate reaction was WTF – that just plain makes no sense to me. There’s a really good reason that ice water is a time-honored hash extraction method – the trichomes (and many other good things found in the flower) are water soluble, the colder the better. Why the hell would anyone want to flush much/most of the THC and other medicinal substances out of their flower before infusing it in a base oil for further use? That seems silly stupid, not to mention incredibly wasteful, to me.

  15. To clarify a factual inaccuracy in my previous post, I realize that of course the trichomes don’t actuallydirectly dissolve in the water, they remain in suspension. The coldness simply helps to dislodge them, then typically a series of ever-finer mesh screens are use to separate them from the water by trichome size, as sativas and indicas (for example) have very different sized trichomes. The “sweet spot” size is very strain-dependent. Anyway, the point is still that water dissolves (OR washes away) much stuff you very much want LEFT in your medicine. So don’t do it!

  16. I’ve been reading your website and using your tricks for awhile now. I’m about to do an extraction with my MBM2e. Since you mentioned it, should I use MCT instead of organic Coconut oil? I will be using the Coco budder for baking cookies and brownies mainly. I’ve also invested in a Nova and this will be the first extraction using buds processed by the Nova.
    I await your response and thank you for your website!

  17. Well Darrell, I am definitely going to try your spray method. Hopefully I don’t blow up my Magic Butter machine. I usually use a crock pot method. I do not disagree with anyone’s opinion but personally, I love the smell of a nice sensi bud but I don’t want to chew it and evidently neither does 80% of my recreational clients. Tasteless cannabis is the golden ticket. Yep. I kid you not. Love this website.

    1. As long as the MB machine does not create any type of “spark”, which I hypothesize it does not, you will not have any trouble using this method in that machine.
      My method is to spread the cannabis on a cookie sheet. Decarb in the oven at 240 for 60 mins. Cool for 10 mins. Spray and let set for 15 mins. Then into the crockpot for 6 hours. So you only need to change last step and should get same or better results.
      Blessed be and merry met.
      May the Goddess always shine a smile upon all your good works.

  18. Many cannabutter/oil recipes have you mix the herb, butter/oil, and several cups water before cooking it down. IMO this lengthens the process and is messy. So I decarb at 240F for 30 minutes, then tie it up tight in cheesecloth like a bouquet garni. Then I put a large sealable Mason jar in a crockpot with water AROUND the jar (not in it!), put the bouquet garni into the Mason jar and pour melted coconut oil or butter on top, set the crockpot on low (~140F) and leave it alone for 24 hours. At the end I just pour the oil into its original container, squeeze the bouquet garni into it to reclaim any remaining oil or butter, and refrigerate or freeze. No watery/weedy sludge to separate from water and no mess in the sink. Works great every time!

      1. Works like a charm. Just an aside: I noticed that the weed/cheesecloth packet still retains up to 1/4 c. oil even after squeezing. So after wringing it out, I put the packet in a funnel over an empty jar, and pour small amounts of boiling water over it, squeeze some more, and repeat several times until the jar is full of water/oil. Then I put the cap back on, put on its side in the frig for an hour, then open and pour the water out. The hardened oil remaining recaptures quite a few doses that would have otherwise gone down the drain! (Or you can just make weed chai with packet….)

        PS Please keep our NoCal farms in your wishes!

        1. I’ve been doing what I call the ‘wash method’ for years – butter or oil, crockpot or MB Machine, same process. Once I’ve wrung it out, I run more oil / butter through it until what’s running through it is clean. I usually get about 4 cups of wash butter or oil and use that as the starting base for my next cook.

  19. If your a serious non lover of the taste of coconut cannabis oil I’ve read the stovetop method with 2 inches of water helps filter out what it’s able to during the cook. I enjoy it so have never tried to see a difference. Besides I’m a MB2 owner and going back to possible scorched batches is not in my future.
    I am not keen on the coconut oil alone , I find it lacks what I enjoy about the flavor of the oils I make. Yet I love it when it’s been combined.

  20. The chlorophyll is what makes cannabis rough to smoke and gives headaches when there’s too much in it (dried too fast), that’s why it’s got such a bad reputation.
    Never heard about “blanching” the weed, what I’ve tried (with some success) is water curing my weed in distilled water. It works trough reverse osmosis, the water absorbs all the extra nuts that are still left in the plant and washes out all the chlorophyll.
    The resulting weed is more compact/potent, depending on how long you cure will lose all the flavor and aroma, but a very smooth smoke.

    It’s good ninja-weed if you want to smoke without anybody noticing, it might also be a good option for edibles to remove the grassy taste if people don’t desire that.

  21. I have just made my first cannabutter using cannabis oil (that I made myself, with my first plant ?). It is SUPER potent and I want to use it to make a cream for my son. He has a little patch of dermatitis on his arm. I was previously putting a tincture on it, but my husband said he smelt like a bong ? so I stopped that. Can you tell me what I would add to give it that ‘creamy’ texture. I can’t wait to try it.

  22. I tend to get a headache with edibles, and green dragon. I did some researchand found that some people are sensitive to chlorophyll. Headaches were a common side effect. I blanched my first batch, So i can’t give my results yet. Do you have a suggestion where a headache may come from?

  23. I tested a 1/4 tsp of the canna butter, and wow! I didn’t have a headache during or after. It still had a weedy tastye, but not as pungent as other non-blanched oils I have made. I may use this method again, for more delicately-flavored cookies that get overpowered with the chlorophyll. It doesn’t take much longer than any other butter i make. It also really is a beautiful end product. Worth the effort. I like the weed flavor on brownies though….

    1. Yep I agree. I bought Cuisinart® Perfectsteep™ Tea Bag Infuser in Stainless Steel/Green from Bed, Bath, Beyond and a countertop boiler. You put the broken up, de-stemed bud in, not too packed and when the little boiler is boiling you drop them in for 5 minutes. The great part is the infusers have long chains that hang over the side so you just lift out. Then you immediately put in a bowl of ice water for exactly one minute. Then I squish out the water and scoop out the mush and spread it on a parchment covered cookie sheet and pop it in the oven on 225 for about 1 hour to decarb. It is still a little damp but that is ok. From there I roll it up in a cheesecloth like a huge joint and tie with kitchen string crisscross to form a quid nice and tight then I add it to my pre processed kosher no salt butter which the bad stuff has been separated and taken out after refrigeration, I never ever forget my liquid sunflower lecithin, then you pop it in the crockpot on low for 24 hours and flip it whenever you remember. When 24 hours are up, I squish and squeeze and twist some more until the reefer bundle is dry and I have the most potent killer best tasting canna butter in town. This is my personal Kentucky Fried special seasoning secret. Why am I telling all of you? Why not? Enjoy. Eight hours of happiness. If you start coming down, eat something fatty, like burger or avocado to re-activate. If you are done, eat sugar. Have fun! We Miami people NEVER take one bite.

  24. Good morning!

    I recently was recruited to do some edible cooking for an important person in my life. I can cook, but I am not a cannabis user (I’ve tried several times and always have a horrible experience). I spent quite a lot of time on your website over the last few weeks trying to educate myself before I made the cannabis coconut oil I’ll be cooking with. Last night, I finally did it… I baked my cannabis for 60 minutes at 220 (which was less than your suggestion but I have a powerful oven that tends to get hotter than most). After it cooled, I put it in a crockpot on low with the coconut oil and sunflower lecithin, made sure it was combined, and let it cook overnight (about 11 hours). This morning I strained it, and it’s super dark brown.

    Is it still useable?

    Is it still effective?

    And what on earth did I do wrong?

    Also, thank you for such a thorough website. Bc I am not a cannabis user, the way your website is presented is appealing and informative to me. I didn’t have to dig through canna culture lingo to understand.

  25. I agree, I’m not washing mine first either!
    I’m no pro, but I purchased a magic butter machine 2 and I absolutely love it! Plus love the Nova debox! Love both!
    I’ve cooked a batch or two every day for a week.. everything turns out much nicer in MBM than doing for hours over a double boiler. I purchased several of your books oks including Dazed and Infused. I just downloaded it! Can’t wait to go read.. headed there now. I’m 61. Been using herb since I was 14. Had 2 back surgeries got on opioids bad.. 3 yrs clean now. Only herb..
    Saved my life! Thank you Lord for the awesome herb! Grateful and Happy. Thank you, Char (:

  26. Hi! I have enjoyed your site and have learned a lot as I am starting to learn to make edibles and tinctures since I want to get away from smoking. I was wondering if you have used a Ninja Foodi/Insta Pot to process any of the oils/butter? I found a technique for decarbing in a mason jar with the pressure feature along with another for infusing the butter. I have processed 2 ‘batches’ so far and have been excited about the results!

    I have been chronically ill for almost 9 years and began with a lyme disease diagnosis. I call it the giving disease, because it has just kept on giving me other illnesses! Fibro, CFS, demyelinating neuropathy, immune disorders, sjogrens, and I am waiting on some additional results right now for lupus, crohn’s, and others. I am currently about 50lbs underweight and struggling! I recently have discontinued many prescriptions and cannabis is the ONLY thing that has provided REAL relief. Thank you for sharing your experiences and knowledge!!!!!!!!

    1. I haven’t used my instapot for this purpose yet. I have a backlog of experiments on the docket right now (and have for the past couple of years 😉 If you’d like to share your method, you can comment here and I’ll try it! xoxo -CT

  27. I love cannabis and like the flavor in m smoke, however I will say cannabutter used in a recipe for the most part makes me gag. I hate the skunk taste in my food. I don’t believe that blanching does anything for pesticides or chemical removal, however it does “significantly” lessen the terpenes and chlorophyl taste that gets extracted into the butter or oil without any noticeable loss of THC.
