Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Calf's Chitterlings, Fraise, or Crow
Ingredients
Directions
Prepare
Wash and cleanse the chitterlings thoroughly.
Soak them in salt and water overnight.
Boil in water for 15 minutes, then dip in cold water and drain.
Cook and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's chitterlings
- Form the main body of the dish, becoming tender through gentle simmering.
- Flour
- Thickens the reduced gravy into a smooth sauce.
- Bacon
- Adds smoky, savoury fat and flavour to the cooking liquid.
- Vinegar
- Adds sharp acidity that brightens the rich gravy.
The step that matters
Simmer gently until done. Vigorous boiling toughens meat proteins and can break the pieces apart, so a gentle simmer keeps the chitterlings tender and intact.
Swap the onion
How well each one fits the dish's main ingredients (pepper, flour, vinegar, cucumber, butter, parsley):
- Shallotfits better
