Why it works: Onion and beef are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 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
- Onions
- Softened in butter, they build the savory base of the soup.
- Flour
- Browned with butter, it thickens the soup and adds toasty, nutty flavor.
- Curry powder
- Supplies the spiced aroma that defines the soup.
- Sherry wine
- Added at the end, it adds a bright, fruity acidity and aroma.
The step that matters
Browning the flour. Flour cooked in fat must brown evenly to develop flavor without burning. Scorched flour turns bitter and dark, and it cannot be fixed once burnt, so cook it slowly while stirring.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, beef, sherry, wine):
