Mountain Oysters Mountain or Prairie Oysters From Richard Harter's Web Site Mountain Oysters, also known as Prairie Oysters, are that part of the male animal which is removed in his youth that he may thereby be more tractable and less, uh, masculine. They are considered to be quite a delicacy.
Some butcher shops sell bull testicles.
These are good but the best source is from young animals. If the mountain oysters are large, cut them into bite sized chunks. Dust the mountain oysters in the flour and saut in a pan of hot oil or deep fry. They should be tender on the inside and crisp on the outside.
