Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main vegetable flavor and tender texture once cooked.
- Milk
- Forms the liquid base of the sauce and carries the asparagus flavor.
- Butter and flour
- Creamed together and stirred in, they thicken the milk into a smooth sauce.
- Heavy cream
- Adds richness and fat, making the sauce creamier and smoother.
The step that matters
Stirring the butter and flour into the hot milk. Adding the flour mixture to hot liquid while stirring helps it disperse evenly, so the sauce thickens smoothly without lumps.
