How to Make It
Prepare the adzuki bean truffles. Combine the adzuki paste and powdered sugar in a small bowl and mix gently using your hands. Form the mixture into 12 balls about 1 inch in diameter. Set them on a plate and cover with plastic wrap. Refrigerate or freeze while you are making the cupcakes.
Decarboxylate the cannabis. Preheat the oven to 250°F. Put the cannabis in a small, heat-proof baking dish and place in the oven. After 15 to 20 minutes, check the temperature of the cannabis with your digital temperature gun; once it has reached 250°F, let it bake for 30 minutes, checking the temperature frequently. (In addition to decarboxylating, you are removing any moisture left in the plant material.) If it goes over the correct temperature for too long, it will burn, the THC may convert into CBN, and you will lose potency. Remove from the oven and set aside to cool. If not using immediately, store the cannabis in an airtight container in a dark place for up to 2 months.
