Why it works: Capsicum and tomato 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Add bulk and a savoury, meaty texture as they soften in the pan.
- Potatoes
- Add starch and body, holding their shape while absorbing some of the sauce.
- Soya sauce
- Adds salty, savoury depth that builds the flavour of the sauce.
- Tomato ketchup
- Contributes sweetness and acidity that balance the chili heat.
- Ginger-garlic paste
- Provides aromatic pungency when fried in oil at the start.
The step that matters
Cook until the vegetables are tender, then remove from heat.. Potatoes need enough time to cook through, while overcooking softens capsicum and mushrooms. Stopping at the right moment keeps each vegetable tender but still with some bite.

Fit is the average pairing score against onion, capsicum, mushroom, potato, garlic, sauce, tomato. 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).
