Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Asparagus
The main vegetable, cooked in boiling water until tender.
Butter
Provides fat and richness, and forms the base of the sauce with the flour.
Flour
Thickens the sauce when cooked with melted butter and liquid.
Milk
Adds liquid and body to the white sauce.
Cream
Adds richness and smoothness to the sauce.

The step that matters

Adding the liquid to the roux. Adding the hot liquid gradually while stirring keeps the flour mixed in evenly, so the sauce thickens smoothly without lumps.
