How to Make Criadillas (aka Bull Fries or Rocky Mountain Oysters)

Updated on May 3, 2019

Cooking Bull Testicles

Criadillas, also known as Rocky Mountain oysters, bull fries, or bull testicles, are a culinary tradition in many countries. The recipe is simple and easy to execute.

This dish might sound crazy and even disgusting for many people, but for those who are interested in tasting and trying something different, criadillas will satisfy such cravings. Between you and me, if we can set aside for a moment the origin of the main ingredient, the dish itself is exquisite.

This dish is most common in areas that enjoy bullfighting. It is said that after the bull is killed in the ring, the toreador-matador must taste the testicles of the slain bull as a show of strength and absolute victory.

Ingredients

  • 1/2 kg bull fries, testicles
  • 1/2 teaspoon salt (I prefer sea salt)

Preperation

  1. Clean the membrane by removing it from the testicles by gently cutting it as it is shown in the pictures.
  2. Cut the testicles into long and thin pieces and wash them thoroughly.
  3. Boil plenty of water and place testicles inside, one by one. Let them boil for about 5-8 minutes.
  4. In the meantime, boil in different pan one more litre of water.
  5. When testicles are ready, you need to re-wash them again with prepared water.
  6. Put olive oil on the pan and let it warm for 2 minutes. Add testicles, salt, pepper, onion, and any other spices you like. Allow them to fry until the colour becomes brownish-golden.
  7. Serve with fresh lemon garnish.
