Why it works: Pepper and tomato match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 17,913 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: peanut (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the peanut paste
If using peanuts, make homemade peanut paste: remove the peanuts' shells, roast them on a baking sheet in a hot oven or in a large skillet on the stove, stirring often, then remove the skins.
Place the peanuts in a saucepan, add enough water to partially cover them, and bring to a slow boil, stirring often.
Reduce heat and crush peanuts with a potato masher.
Cook the greens
Fry the onion and green pepper in hot oil in a large saucepan until they begin to become tender.
Add tomato and spinach or greens and a quarter cup of water.
Reduce heat and cover.
Simmer until all is tender, stirring occasionally.
Finish and serve
Add spices and peanut butter or peanut paste.
Reduce heat to lowest possible.
Stir until sauce is smooth.
Serve with fufu.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peanut butter
- Provides the fat and nutty body that thickens the sauce into a smooth, rich texture.
- Spinach
- Forms the leafy base of the stew, softening as it simmers into a tender, cohesive mass.
- Tomato
- Adds acidity and moisture that brightens the stew and helps break down the greens.
- Onion
- Builds a sweet, savory aromatic base as it softens in hot oil.
- Green pepper
- Contributes fresh, slightly bitter vegetable flavor and some body to the base.
The step that matters
Stir until sauce is smooth. Peanut butter can separate or clump when added to hot liquid, so keeping heat very low and stirring continuously lets its fats and solids emulsify into an even sauce.

Fit is the average pairing score against onion, pepper, tomato, spinach. 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).
