Why it works: Tomato and capsicum match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 9,700 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Directions
Gently stew the tomatoes with shallots, chilies, ham, and rich gravy.
Stir often until the tomatoes reduce to a smooth pulp.
Rub the mixture through a sieve into a clean saucepan.
Add a few more spoons of rich gravy or Espagnole and salt if needed.
Boil the sauce, stirring well for 10 minutes, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red tomatoes
- Form the bulk of the sauce and break down into a smooth pulp.
- Shallots
- Add aromatic sweetness and depth to the sauce base.
- Rich gravy
- Adds savoury body and moisture to the sauce.
- Lean ham
- Contributes savoury, salty flavour to the sauce.
The step that matters
Rubbing the mixture through a sieve. Pressing the stewed tomatoes through a sieve removes skins and seeds and breaks down fibres, which gives the sauce its smooth texture. Skipping or rushing this step leaves the sauce grainy.

Fit is the average pairing score against tomato, capsicum, ham. 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).
