So I've got two big, yummy looking artichokes. I've only cooked artichokes once or twice before and I'll I did was boil them in water and I remember it seemed to take forever before I could eat them. Anyone with any tips for cooking them? I do have a crock pot. I was thinking about trying them in there, but have no idea if I should do it on low or high or how long they would need on either temp.
