Freeze it all for at least 2 hours (longer to get the center, if you’ve made more than a cup). Remove, allow to thaw to room temp (or the shock will break your dish and waste all your precious oil), then place back in the oven for just long enough to liquefy and thin out the oil for better straining.

The Ultimate Cannabutter Experiment was repeated twice, with different types of cannabis used for each batch, for eight total butter samples. Two different laboratories analyzed each set of samples along with the cannabis used to create the infusions, allowing us to confirm trends by comparing the data sets.
Kat’s method decarbs the trim in the oven at 220ºF for 20 minutes in a Pyrex dish sealed with foil. After adding the lecithin and clarified butter, the dish is re-sealed and returned to the oven for 90 minutes, stirring once halfway. Finally, the infusion is cooled and then frozen for several hours before lastly being thawed, melted and strained. While it’s a time-intensive process with many steps, the fans who follow Kat’s blog swear by its effectiveness.
When finished cooling from the second heating, you can either freeze your material in the dish, if it’s Pyrex, or pour the entire batch into a freezer-safe container.
Grind your herb as finely as possible. Sprinkle evenly over the pie dish.
Once removed, preheat the oven again to 220ºF.
Kat Smiles from Bad Kat’s Cannapharm, a popular online resource for cannabis cooks, developed our second method for making cannabutter. In order to increase bioavailability of THC, Kat includes an emulsifier called lecithin with her infusion. While adding lecithin won’t result in extra potency that the lab can measure, the concept of “bioavailability” means that the same amount of THC will feel more potent in your body.
Kat writes: “Unfortunately there is a lot of discrepancy on decarboxylation. If you have freshly harvested wet cannabis, it’s going to take several hours for it to first become smoke-dry, then decarb and activate. If you feel your material is very fresh, but smoke dry, feel free to experiment by adding an extra 10 – 15 minutes. If it’s very old, a faded, more pale shade of green or brown, and you feel it may have crossed a border or two to get to your home, keep to the guide and do not exceed 20 minutes.”
Traditionally, cannabutter is the basis for marijuana cookery and as the author of The Official High Times Cannabis Cookbook, I’ve been approached by people tou
