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, Fricasseed, White, with Onions
Ingredients
Directions
Prepare the tripe
Cut the tripe into pieces 3 inches long and 2 inches wide.
Wash the tripe in cold water, then dry it with a cloth.
Simmer and season
Place the tripe in a bright stewpan with 1½ cups of new milk.
Simmer gently for 2 hours, stirring frequently to prevent burning.
Peel the onions and add them to the stewpan.
Simmer for an additional 30 minutes.
Remove the onions from the stewpan and chop them finely.
Season the onions with salt, sugar, mustard, white pepper, and grated nutmeg.
Finish and serve
Stir the chopped onions and baked flour into the milk.
Simmer for another 15 minutes.
Quickly stir in the thick cream or fresh butter.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Provides the main body of the fricassee, becoming tender through long gentle simmering in milk.
- New milk
- Forms the cooking liquid that softens the tripe and becomes the base of the sauce.
- Onions
- Add sweetness and flavour to the milk as they cook and break down when chopped.
- Baked flour
- Thickens the milk into a smooth sauce that coats the tripe and onions.
- Thick cream or fresh butter
- Stirred in at the end to enrich the sauce with fat and a silky texture.
The step that matters
Stirring in the cream or butter. Adding dairy fat to a hot, thickened sauce and stirring quickly keeps it smooth and prevents it from separating or curdling under prolonged heat.
Swap the white pepper

- Cinnamonfits better
