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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Browning in butter builds a sweet, savoury base for the gravy.
- Butter
- Fat that carries the onion's flavour and helps it brown.
- Canned tomatoes
- Provide acidity, moisture and body to the gravy around the meat.
- Cold meat
- Main protein, which warms through in the simmering tomato gravy.
The step that matters
Thicken the gravy only if needed. Tomatoes and water give a thin sauce, and adding starch before the meat has warmed through can leave the gravy pasty or lumpy. Thicken gently at the end so the gravy coats the meat without becoming gluey.
Swap the tomato
How well each one fits the dish's main ingredients (onion, butter, meat, pepper):
- Potatofits better
- Capsicumfits better
- Mustardfits about as well
- Tomatothe original
Fit is the average pairing score against onion, butter, meat, pepper. Candidates are from the same food group and used in at least 100 recipes.
