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

What each ingredient does

Lobster or crab
Provides the main meat and sweet flavour of the sauce.
Butter
Carries flavour and enriches the sauce with fat for a smooth texture.
Flour
Thickens the milk into a smooth sauce when cooked with the butter.
Milk
Forms the liquid base of the sauce, adding body and mild sweetness.
Cream
Adds richness and a silkier mouthfeel to the finished sauce.

The step that matters

Adding the flour and milk. Flour must be cooked in the melted butter before milk is added gradually, and the sauce kept moving, so it thickens smoothly without lumps.

Swap the lemon
