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 ↓

Butter and flour 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
- Spinach
- Forms the bulk of the dish; cooking and drying it concentrates its flavour and gives body.
- Butter
- Adds richness and fat, carrying flavour and giving the spinach a smooth texture.
- Flour
- Thickens the mixture as it cooks, helping it become smooth and thick.
- Beef jelly
- Moistens the mixture and adds meaty savouriness and body.
- Cream
- Adds richness and a smooth, creamy texture to the finished dish.
The step that matters
Cook the spinach until dry. Spinach holds a lot of water; if it stays wet, the flour cannot thicken it properly and the mixture turns thin and watery. Cooking it down over low heat drives off moisture before the flour and jelly are added.
