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 ↓
Chopped Spinach Thickened with Flour
Ingredients
Directions
Cook the spinach according to package instructions.
In a saucepan, melt the butter over medium heat.
Add the flour to the melted butter and mix thoroughly.
Stir in the cooked spinach and cook for about 5 minutes.
Add the milk and season with salt and pepper, reheating while stirring constantly to prevent burning.

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 vegetable flavor of the sauce.
- Butter
- Adds richness and fat, and carries flavor through the sauce.
- Flour
- Thickens the butter and liquid into a smooth, cohesive sauce.
- Milk or cream
- Supplies the liquid that turns the mixture into a creamy sauce.
The step that matters
Stirring while reheating after adding the milk. Milk proteins and starches can scorch on the bottom of the pan if left unstirred over heat. Constant stirring keeps the heat even and the sauce smooth, preventing burning and lumps as it thickens.
Swap the spinach
How well each one fits the dish's main ingredients (milk, butter, pepper, flour):
- Potatofits better

- Chivefits about as well
- Spinachthe original
Fit is the average pairing score against milk, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
