Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 17,923 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Sauce
Ingredients
Directions
Make the sauce

Add salt and cayenne pepper, then the butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stewed tomatoes
- Provide the main body and tomato flavour of the sauce.
- Flour
- Thickens the strained tomatoes into a smooth, cohesive sauce.
- Butter
- Adds richness and a glossy finish to the sauce.
The step that matters
Work the flour smoothly into the tomatoes. Flour clumps if added to hot or unevenly mixed liquid. Stirring it into the cold strained tomatoes first disperses the starch so it thickens evenly when heated.
Flavor stand-ins for the walnut
How well each one fits the dish's main ingredients (tomato, flour, pepper, butter):
- Beansbetter flavor fit
- Chickpeabetter flavor fit
- Black-eyed peabetter flavor fit
- Walnutthe original
Fit is the average pairing score against tomato, flour, pepper, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
