Why it works: Butter and cheese are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Tomato Rarebit
6 hot dishesIngredients
Directions
Make the tomato base
Put 1 tablespoon butter in a chafing dish or saucepan and brown 1 small chopped onion.
Add 1 cup thick, canned tomato, 1 teaspoon salt, a pinch of cayenne pepper, and a pinch of sugar.
Stir until it boils.
Add 4 tablespoons grated cheese and 3 raw eggs.
Stir, and as soon as the eggs are done, serve on crackers or small slices of toast.
Prepare the bacon and cheese
Put several thin slices of bacon in a frying pan and fry several minutes on each side.
Put them on a baking plate in the oven and cover with slices of cheese, with bits of butter on top.
Bake 5 or 10 minutes or till the cheese is thoroughly melted.
Serve immediately.
Make the ale cheese
Put 1 gill Bass's ale in a saucepan with 1 tablespoon Worcester‑shire sauce and 1 saltspoon cayenne pepper.
As soon as it boils briskly, add 1 pound rich grated cheese and stir until melted and very hot.
Have 6 slices of hot fresh toast on 6 hot dishes, pour the cheese over the pieces of toast, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the tomato and cheese mixture into a creamy, thickened sauce when heated.
- Cheese
- Melts into the sauce, providing richness, body and savory flavor.
- Canned tomato (in the method)
- Adds acidity and fruity flavor that balances the rich cheese.
- Bass's ale
- Thins the cheese mixture and adds a malty, slightly bitter flavor.
- Onion
- Browned in butter to add sweetness and aroma to the base.
The step that matters
Stir the eggs in gently over heat. Eggs thicken when heated but scramble if they get too hot or are overcooked, so the sauce turns grainy instead of smooth and creamy.
Swap the onion
How well each one fits the dish's main ingredients (butter, cheese, sauce, pepper, egg):
- Capsicumfits better
- Mustardfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against butter, cheese, sauce, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
