^the decarbing is important, don't skip this step. it's what turns most of the plant's THCA to yummy, bioavailable THC.
I also recommend smothering the firecracker surfaces with coconut oil or butter so the decarbed weed is covered with coconut oil when squished together. Saturated fats are important for extracting THC out of the decarbed weed flowers and in to your food's fat source.
