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.
