Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Tripe

Ingredients

Directions

Prepare the tripe

  1. Clean the fresh tripe well, removing excess fat, and cut it into pieces about 2 inches by 4 inches.

  2. Place the tripe in a stew pan and cover it with equal parts milk and water.

  3. Boil gently until tender, about 1 hour if pre-prepared, or 2-3 hours if entirely undressed.

Cook the onions

  1. Peel the onions and boil them separately until tender, about 45 minutes.

  2. Drain the onions and trim the tops until they are nice and white.

Serve

  1. Combine the tripe and onions in a serving dish, removing any floating fat.

  2. Serve with bacon or sausages, and add vinegar and mustard if desired.

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

What each ingredient does

Fresh tripe
Forms the main body of the stew, becoming tender with long gentle simmering.
Milk
Adds richness and a mild, creamy flavour to the cooking liquid.
Onions
Contribute mild sweetness and soft texture to the finished dish.

The step that matters

Boil gently until tender. Tripe is tough collagen-rich tissue that only becomes tender with long, low-heat simmering. A hard boil can toughen and shrink the meat and make the liquid cloudy, so keep the heat low and check for tenderness rather than rushing.

Swap the mustard

The recipe marks mustard as optional. How well each one fits the dish's main ingredients (milk, onion, vinegar):

  1. Potatofits better
  2. Mustardthe original
  3. Capsicumfits about as well
  4. Cucumberfits less well

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