Why it works: Tomato and corn match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,099 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that softens the onions and carries flavour into the base.
- Onions
- Sweetness and aroma that build the soup's savoury base as they soften.
- Flour
- Thickens the soup slightly as it cooks with the butter and tomatoes.
- Tomatoes
- Main body and acidity of the soup, thickened further once sieved.
- Corn
- Adds sweetness and body, cooked long enough to soften in the soup.
- Egg yolks
- Enriches and thickens the soup for a smoother, richer texture.
The step that matters
Stirring the egg yolks into the soup. Egg yolks thicken when heated, but if the soup is too hot or boiling when they are added they can scramble into lumps. Mixing them with cream or milk first and stirring gently helps them blend smoothly.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, onion, flour, tomato, sugar, corn, egg):
- Cinnamonfits better

- Jalapenofits better
- White pepperthe original
Fit is the average pairing score against butter, onion, flour, tomato, sugar, corn, egg. Candidates are from the same food group and used in at least 100 recipes.
