Bahahahaha, these things are big in Texas. Even some restaurants have them on their menu. We called them Mountain Oysters. I have even cooked them, BUT NEVER HAVE EATEN ANY. My X-husband was a veterinarian and all the vets in the area would save the testicles from bulls that they castrated. Then once (or twice) a year, they would get together and have a Mountain Oyster fry. Peel 'em, slice 'em, batter 'em and fry 'em, just like chicken, except they are boneless, of course. When they float to the top they are done (BARF). I've cooked many a strange thing, but believe me I have never eaten any of it!!!!!

Rocky Mountain oysters, mountain oysters, prairie oysters, Montana tendergroin or swinging sirloin are culinary names given to boar or bull testicles. They are usually peeled, coated in flour, pepper and salt, sometimes pounded flat, then deep-fried. Boar (hog) "Mountain oysters" or "Rocky Mountain oysters" are served in some Mid-west areas such as in Illinois, and Iowa.
