Why it works: Tomato and rice match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,065 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Marrow
- Forms the bulk of the soup and gives it its main body and mild flavour.
- Tomatoes
- Add acidity and a bright red colour to the soup.
- Onion
- Adds savoury depth as it softens gently in the butter.
- Milk
- Adds richness and a creamy texture to the liquid.
- Rice
- Thickens the soup as its starch releases during simmering.
- Butter
- Carries the onion's flavour and adds richness to the start of the soup.
The step that matters
Cook slowly until all are tender. Milk can scorch and stick to the base of the pan over high heat. Gentle, slow cooking keeps the milk smooth and lets the vegetables and rice soften evenly.
