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

What each ingredient does

Eggs
Thicken the sauce as they cook and give it a rich, custard-like body.
Butter
Adds richness and fat, and carries flavour through the flour base.
Flour
Thickens the milk and butter mixture into a smooth base.
Milk
Forms the creamy liquid base that gives the sauce its body.
Asparagus juice
Provides the main vegetable flavour and liquid for the sauce.

The step that matters

Gradually mix the hot mixture with the beaten eggs, stirring constantly. Adding hot liquid to eggs too quickly can scramble them. Pouring slowly while stirring gently raises the egg temperature evenly, so the eggs thicken the sauce smoothly instead of curdling.

Swap the asparagus
