To Boil Tripe

Ingredients

Directions

Prepare the tripe

  1. Wash the tripe well in warm water.

  2. Trim off all the fat from the tripe.

  3. Cut the tripe into small pieces.

  4. Boil the tripe in enough water to cover it for five hours.

  5. After four hours, pour off the water.

  6. Season the tripe with pepper and coarse sea salt.

Simmer the tripe

  1. Place the tripe in a pot with equal parts milk and water.

  2. Boil the tripe in the milk and water for one hour.

Make the sauce

  1. In a separate saucepan, boil ten or a dozen onions until soft.

  2. Drain and mash the onions.

  3. Wipe out the saucepan.

  4. Add the mashed onions with a bit of butter rolled in flour and a ⅓ cup of cream or milk. Let the mixture boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tripe
The main ingredient; long simmering softens its naturally tough, chewy texture.
Milk
Gives the simmering liquid and the sauce a creamy, mellow body.
Cream or milk
Adds richness and smoothness to the sauce.
Onions
Softened and mashed, they add sweetness and body to the sauce.
Butter
Adds fat and richness, and cooks with flour to form a thickening base.
Flour
Thickens the sauce when cooked with butter and boiled.

The step that matters

Boiling the butter and flour into the sauce. Flour only thickens fully when it is heated in the liquid until the sauce boils. If it is not boiled, the sauce stays thin and can taste pasty or raw.

Swap the onion
