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 ↓
Tomato Soup
Ingredients
Directions
Make the tomato base
In a separate pan, melt the butter and add the tomatoes.
Cook the tomatoes until tender, then press them through a sieve.
Thicken the stock
In a pot, bring the weak stock to a boil.
Add the crushed tapioca and boil for 20 minutes.
Combine and serve
Combine the tomato juice with the stock and bring to a boil.
Season with salt and cayenne pepper.
If desired, stir in a little cream after boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main flavour and body of the soup once cooked and sieved.
- Tapioca
- Thickens the stock as it boils, giving the soup body.
- Butter
- Adds fat and richness to the tomatoes as they cook.
- Weak stock
- Forms the liquid base that carries the tomato flavour.
The step that matters
Boiling the tapioca. Tapioca thickens only when it boils long enough for its starch to swell and gelatinise. Boiling it for the full time ensures the soup reaches the intended thickness and a smooth texture.
Swap the tomato
How well each one fits the dish's main ingredients (butter, ham, pepper, cream):
- Potatofits better
- Onionfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against butter, ham, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
