I drank cactus liqueur in Gozo once. Actually, it was more than once because after the barman poured us our first shot, he kept the shots coming all night. I only mention this because that is the only time I’ve done anything with a cactus other than have it sitting spikily around the house while hoping remembering to water it once a year is enough to make it not die. Although, reading through Erbology’s info on nopal cactus, and how popular it is in Mexico, a vague recollection of eating a cactus quesadilla in a Mexican restaurant somewhere near Charing Cross is forming in my mind. Still, let’s just say my experience with eating or drinking cactus is limited.
