If I had that many I would try canning them. It sounds like a lot of work but being able to have them later would be worth it to me. I love the artichokes in salad and on pizza. (Also, just open a jar and snack is good too.) But I am not sure if they would last that long in my house. My family loves cooked artichokes. I usually cook them in the pressure cooker when cooking more than one. I have a very small 5 cup rice cooker that I use when there is just one. (I can set it for an hour and it stops when done.)
