OH! Another use for Cardoon!!! I have grown Cardoon here in Canada, and love the plant anyway, and am going to plant a long row of it (have tons of seed I saved, that IS viable, I tested). So...I need more technical info on the SCIENCE of using Cardoon...how much of what part to how much water, temps, extraction times, etx...and if we are looking for a specific testable PH or something.... I have used animal and vegetable rennet for many years, but if I can do my own with Cardoon I would be happy to try it!
