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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 moisture of the fritter mixture.
- Eggs
- Bind the mixture together and help it set while frying.
- Flour
- Adds body to the mixture so the fritters hold their shape.
- Butter
- Adds richness and fat that helps the fritters brown.
The step that matters
Frying the spoonfuls in hot fat. If the fat is not hot enough, the fritters absorb excess oil and turn greasy and pale. Hot fat sets the outside quickly and gives a golden crust, so heat the pan before dropping in the mixture.
Swap the tomato
How well each one fits the dish's main ingredients (butter, egg, pepper, flour, sugar, vinegar):
- Capsicumfits better
- Shallotfits better
- Mustardfits better
- Tomatothe original
Fit is the average pairing score against butter, egg, pepper, flour, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
