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
- Beef shank
- Long slow boiling draws flavor and body into the broth.
- Potatoes
- Starch thickens the broth slightly and adds body to the soup.
- Fresh cream
- Adds richness and a smooth, mellow texture to the finished soup.
- Flour
- Thickens the cream mixture so it blends smoothly into the soup.
The step that matters
Adding the cream and flour mixture. Cream mixed with flour and stirred into a hot liquid can separate or form lumps if not blended first. Mixing them together before adding, and adding them just before serving, keeps the soup smooth and avoids overcooking the dairy.
