Rocky Mountain Oysters, A Denver Delicacy?

admin April 21, 2011 0

Fans of the specialty cuisine can also find the “oysters” for sale as a specialty item in various markets and restaurants in the Denver area.

How exactly is the dish made? Traditionally, Rocky Mountain oysters are made by first peeling the fresh bull testicles.  After that, they are pounded flat with a mallet and seasoned with a variety of spices including black pepper, seasoned salt, and cayenne pepper.  The type of spices and the amounts used depend of personal taste.  The testicles are then breaded with flour and then either deep-fried or pan fried in oil.  Since the finished product resembles fried oysters, the fried bull’s testicles are often called oysters. Some people claim that this has nothing to do with the name but rather the word “oyster” is a joke due to the fact that Colorado is no where near the ocean.


Although fresh bull’s testicles can be typically purchased in specialty shops for those that wish to partake of the delicacy at home, cooks recommend purchasing frozen, peeled testicles at a grocery store in order to simplify the cooking process.  Cutting the frozen oysters into thin slices instead of pounding them flat also helps to simplify the cooking process.  The slices can then be seasoned and fried.


Fans of Rocky Mountain oysters claim that the dish tastes like liver when properly prepared.  Others simply claim the dish tastes like—chicken! This dish, most often served as an appetizer, is best when eaten with a dipping sauce.  One thing is for sure, eating Rocky Mountain oysters is a Denver tradition; one that will earn you bragging rights for sure.
