American Rocky Mountain Oysters

Rocky mountain oysters, US

Rocky Mountain oysters is a term for a dish made of bull, pig or sheep testicles. The organs are often deep-fried after being peeled, coated in flour, pepper and salt, and sometimes pounded flat. This delicacy is most often served as an appetizer[1] with a cocktail sauce dip.

It is a well-known novelty dish in parts of the American West and Western Canada where cattle ranching is prevalent and castration of young animals is common ("prairie oysters" is the preferred name in Canada, where they may be served in a demi-glace, not deep-fried). In Oklahoma and the Texas Panhandle, they are sometimes called calf fries but only if taken from very young animals. In Spain, Argentina and many parts of Mexico they are referred to as "criadillas," and they are colloquially referred to as huevos de toro (literally, "bull’s eggs"; besides its literal meaning, huevos is a Spanish slang term for testicles) in Central and South America. Rocky Mountain oysters are sometimes confused with lamb fries or animelles (lamb testicles), which are served in a manner similar to Rocky Mountain oysters.
