Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Butter
Ingredients
Directions
Slice the tomatoes and place them in a pan with the butter, carmine, shallot, salt, and pepper.
Cover with a lid and cook gently on the side of the stove until they become a pulp.
Rub the pulp through a fine sieve, re-warm, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and flavor of the sauce once cooked down to a pulp.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Shallot
- Adds a mild, aromatic sharpness that complements the tomato.
The step that matters
Rub the pulp through a fine sieve. Pressing the cooked tomato through a fine sieve removes skins and seeds, which is what gives the sauce its smooth texture.
Swap the shallot
How well each one fits the dish's main ingredients (tomato, butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Shallotthe original
Fit is the average pairing score against tomato, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
