According to MagicalButter.com,
“Note 1: Decarboxylation is only for specific,
rare herbs and exotic flowers. Do NOT attempt with common culinary herbs or fruits, as it will remove their moisture and flavor.
Note 2: Your oven may not be an exact precision appliance; this is normal. All ovens are not created equal. Most operate on an approximation, average, or temperature range for any given value. So, calibrating your oven is essential to smart decarbing and baking. Once it’s done, you can proceed to Phase 2.
Phase 1: Calibrate your oven
- Place an oven thermometer inside your oven, and close the
- Preheat the oven to a desired decarb temperature. In the Decarboxylation Guide below, the great majority of consumers will want to use the first (lowest) temperature
- Once the oven signals that it has finished preheating, take a temperature reading. This will tell you if the oven actually reached the desired temperature you had
If the actual temperature reading on the thermometer differs from your oven setting, then raise or lower the setting by that amount to compensate when decarbing. For example, if your setting is 250°F but the thermometer reads 270°F, then your oven runs hot. You would then compensate by lowering your setting 20 degrees, to 230°F.
1-ounce glass jar with metal lid (silicone containers can also be used but they are not see through)
Sheet pan/cookie sheet
Loose concentrates (shatter, wax, live resin, etc.)
If adding straight to a recipe, in the last 5-10 minutes of decarb place the amount of oil needed for a recipe in a glass measuring cup or small glass bowl in the oven on the sheet tray to warm up. Once removed from the oven, add the amount of liquid sunflower lecithin required for your recipe into the warmed oil (if using) and stir with a toothpick until homogenous. Open the concentrate jar and slowly add the oil mixture while stirring with a toothpick. Cap the jar and shake vigorously until blended. Let settle and add directly into the oil portion of your recipe. I like to use a marshmallow to get any residual medicine out of the jar. A finger also works!
After the decarb time has elapsed, the cannabinoids have changed from their acid form. The bubbles that appear are residual solvent. If you are sensitive to the solvents used, decarb until very few or no bubbles remain. When it looks like glass, it should be solvent free.
The more concentrate is decarbed the longer it will take for the residual solvent to be removed. For example, 12 grams of loose concentrate took 2.75 hours to remove the residual solvents.
HOW TO (CAUTION: EVERYTHING WILL BE VERY HOT, USE OVEN MITTS ETC.)
Preheat oven to 250°F.
Empty loose concentrates into the glass jar and close.
Place the filled jar onto the sheet pan and decarb for 45-60 minutes. Most of any residual solvents should be out of the product after this time. Check the bubbles to see when to stop the decarb process.
Remove the sheet pan from the oven. Wait about 5 or so minutes before opening, so as not to lose any plant constituents.
At this point you can use grain alcohol, oil or another medium to aid in the removal from the jar and continue your processing.
