Rocky Mountain Oysters are a Western culinary oddity tied to Colorado's ranching heritage. Despite the name, they are not seafood but bull testicles, which are peeled, sliced, seasoned, breaded, and deep-fried until golden. The texture is similar to fried calamari and the flavor is mild. They appear on menus across the state — from dive bars and county fair stands to upscale restaurants playing with the novelty. The dish originated from the ranching practice of eating everything after castration, and it has become a tourist rite of passage. The annual Testicle Festival in Deer Trail was famously associated with the dish.
