Why it works: Spinach and pepper are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,400 recipes. Both carry nonanal, which smells fat, citrus. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Provides the main body, color and green flavor of the soup.
- Cream
- Adds richness and a smooth, silky texture.
- Butter
- Carries fat and flavor into the roux.
- Flour
- Thickens the stock when cooked with butter as a roux.
- White stock
- Forms the liquid base that the spinach and roux are combined with.
The step that matters
Cook the roux before adding the stock. Cooking flour in melted butter until it loses its raw taste lets it thicken smoothly; adding it raw or unevenly can leave lumps and a pasty flavor.
Swap the spinach
