Preparation of Dry San Pedro:
Remember to decide if you are using a collinder or cheese cloth for filtering before smashing. If using a collinder, don't smash it up too much.
Take the dried San Pedro (don't worry about spines and core) and weigh your doses. Put these dried dose(s) into a big plastic baggie ("ziplock" heavy duty, better use two; works better). Step on the bag repeatedly (with shoes on, it is a cactus after all) to smash the cacti.
NOTE: If you are using grainules it is already prepared for cooking.
