Jeff the 420 Chef highly recommends you clean your cannabis (especially if your flower is not organic). He has a great technique for leaching out chlorophyll and impurities like pesticides and metals which involves soaking your coarsely ground herb in distilled water for up to 72 hours.
You can always choose to skip this step, but “cleaning” your herb prior to infusing certainly helps to remove much of the chlorophyll and contaminants that contribute to the “weed-forward” flavor in many infused products.
Step 1: Soak
To clean your cannabis, first start by grinding up your herb of choice and soaking it in distilled water for 24-48 hours (making sure to change the water roughly every 12 hours).
Step 2: Blanche
When your water is no longer cloudy, strain your herb through a fine strainer and blanche in gently boiling water for 3-5 minutes (blanching helps to further remove pesticides, pistils, and bacteria often found in commercial cannabis).
Step 3: Rinse & Dry
After blanching, immediately place your nug in a distilled cold-water bath, rinse with distilled water, and dry overnight.
“As the old adage goes, oil and water does not mix. And so fittingly when the two are combined, it can create an environment that is susceptible to mold. That’s why it’s always a good idea to thoroughly dry your flower before infusing if you want a longer shelf life and a more stable product.” – Jeff the 420 Chef
At the end of the day, deciding whether to clean your cannabis or not comes down to a matter of preference. I actually tend to enjoy the pronounced earthy taste of cannabis when balanced with the right botanicals. But if you’re not quite sure if your product is pesticide-free, it’s probably a good idea to take the extra time to clean and blanch your cannabis before infusing. This step certainly helps tame the chlorophyll flavor and makes for a near “tasteless” infusion.
