Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. 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
- Rice
- Thickens the broth slightly as it cooks and adds body to the soup.
- Potato
- Releases starch into the broth, adding body and a mild, filling texture.
- Egg
- Thickens the soup when stirred in and gives it a richer, silkier texture.
- Flour
- Stabilizes the milk and egg mixture and helps thicken the soup.
- Milk
- Adds creaminess and softens the flavor of the broth.
The step that matters
Stirring in the egg, milk, and flour. Adding the egg to boiling liquid can scramble it. Combining it with milk and flour first, and keeping the heat gentle, helps it blend smoothly and thicken without curdling.
