Tripe and Onions

Ingredients

Directions

Prepare the tripe

  1. Clean the tripe and wash it well.

  2. Place the tripe in a saucepan covered with cold water and bring the water to a boil.

  3. Once boiling, remove the tripe and place it in a basin of cold water to wash again.

  4. Scrape the tripe on both sides and cut it into pieces about 3 inches square.

  5. Return the tripe to the saucepan, cover with cold water and boil gently for 5 hours.

  6. After boiling, pour off the water.

Make the dish

  1. Replace the water with milk and bring the milk to a boil.

  2. Parboil the onions, then chop them.

  3. Add the onions to the tripe and milk.

  4. In a small bowl, mix the flour, pepper, salt, and a little cold milk until smooth.

  5. Add the flour mixture to the saucepan and boil for 15 minutes.

  6. Serve hot.

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

What each ingredient does

Tripe
Forms the main body of the dish and becomes tender after long gentle boiling.
Milk
Provides the liquid that cooks the tripe and makes a creamy sauce.
Onions
Add sweetness and aroma as they soften into the milk.
Flour
Thickens the milk into a smooth, lightly coating sauce.

The step that matters

Boiling the flour mixture into the milk. Flour must be mixed smooth with cold milk first, otherwise it clumps; once stirred in, boiling cooks the starch so the sauce thickens fully and loses its raw floury taste.

Swap the onion

How well each one fits the dish's main ingredients (milk, flour, pepper):

  1. Capsicumfits better
  2. Arrowrootfits better
  3. Potatofits better
  4. Onionthe original

Fit is the average pairing score against milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
