Why it works: Potato and rice match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 851 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter 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
- Potatoes
- Provide the body of the soup and, once cooked, soften it into a creamy base.
- Milk
- Adds richness and a creamy texture to the soup.
- Flour or cornstarch
- Thickens the liquid as it heats, giving the soup body.
- Butter
- Adds fat and a rich flavor, and smooths the finished soup.
The step that matters
Thicken soup with flour or cornstarch. Starch must be fully dispersed before or while heating, otherwise it clumps and the soup stays grainy. Starch thickens as it heats, so the soup should be cooked enough for the thickening to set.

Fit is the average pairing score against milk, flour, egg, butter, rice. Candidates are from the same food group and used in at least 100 recipes.
