When I read that you can buy and eat testicles I wondered whether I should try it once, since I'm basically open to anything that tastes good. I wonder how I should prepare them. If I buy testicles are they empty or do they still contain the, err, fluid?   How to properly make them up so they aren't toxic or something anymore?  
I have only eaten bull testicles once; they were simply coated with black pepper and grilled. They're not terribly interesting as meat. They didn't taste of much, and the texture was about like other glands (sweetbreads, for example) -- kind of smooth and not chewy.
