Why it works: Pepper and nutmeg match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 13,015 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Chitterlings or Calf's Tripe
Ingredients
Directions
Prepare
Wash the chitterlings and cut them into pieces.
Place them in a stew-pan with salt, pepper, and 2 quarts of water.
Boil for 2 hours or until tender.
Make the onions
Peel the onions and boil them in plenty of water until soft.
Drain the onions and mash them.
In a cleaned sauce-pan, combine the mashed onions, butter, cream or milk, nutmeg, and a little salt. Sprinkle in some flour, cover, and heat until it boils.
Serve
Once the chitterlings are tender, drain them.
Place buttered toast in a dish, lay the chitterlings on top, and serve with stewed onions.
Season with pepper and vinegar before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chitterlings
- Main protein; boiling until tender turns the tough tissue soft enough to eat.
- White onions
- Mashed and stewed, they provide sweetness and a soft, creamy body to the sauce.
- Butter
- Adds richness and fat, giving the onion mixture a smooth, rounded flavor.
- Cream or rich milk
- Adds moisture and richness, helping the mashed onions become smooth and creamy.
- Flour
- Thickens the onion mixture as it heats, giving it body rather than a watery texture.
The step that matters
Heat the onion mixture after adding flour. Flour must be heated until it boils to cook out its raw starch taste and to thicken the mixture properly; stopping early leaves the sauce pasty and floury.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, cream, nutmeg, flour):
- Spinachfits better

- Shallotfits better
- Onionthe original
Fit is the average pairing score against pepper, butter, cream, nutmeg, flour. Candidates are from the same food group and used in at least 100 recipes.
