Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mutton Rechauffe
Ingredients
Directions
Prepare the sauce
Slice the cold mutton into small pieces.
In a pan, cook the chopped onion in butter until light yellow.
Stir in the flour, then gradually add ½ cup boiling water.
Add salt, pepper, and the egg yolk, mixing well.
Coat and fry
Spread the sauce over the mutton slices, laying them in a shallow dish.
Roll the mutton in breadcrumbs, then dip in beaten egg, and roll in breadcrumbs again.
Fry in hot oil until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mutton
- Forms the main body of the dish, carrying the sauce and coating.
- Egg yolk
- Enriches the sauce and helps it bind and thicken as it blends in.
- Flour
- Thickens the onion and water mixture into a smooth sauce.
- Egg
- Acts as a binder so the breadcrumbs adhere and form a crisp coating.
- Butter
- Softens the onion and adds richness and flavour to the sauce.
The step that matters
Fry in hot oil until golden brown. Oil that is not hot enough lets the coating soak up grease and turn soggy before it browns. Hot oil sets the egg and breadcrumb crust quickly, keeping the coating crisp and the meat inside tender.
Swap the onion
How well each one fits the dish's main ingredients (mutton, egg, butter, flour, pepper):
- Leekfits better
- Shallotfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against mutton, egg, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
