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 ↓

Season with salt, pepper, and butter.
Add the sweet cream and a little flour, then let it scald but not boil.

Serve

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
- Ripe tomatoes
- Provide the main body and flavor of the sauce once stewed smooth.
- Sweet cream
- Adds richness and a smooth, creamy texture to the sauce.
- Flour
- Thickens the cream mixture so it coats the toast rather than running off.
- Butter
- Adds fat for richness and a rounded, savory flavor.
The step that matters
Scald without boiling. Once cream is heated past scalding it can boil and curdle or separate, and flour-thickened sauces can turn grainy. Heating gently and removing from heat immediately keeps the sauce smooth.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, butter, cream, flour):
- Spinachfits better
- Leekfits better
- Potatofits better
- Tomatothe original
Fit is the average pairing score against pepper, butter, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
