Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and give it a rich, smooth body as they set gently with the milk.
- Butter
- Adds fat and richness, and carries flavor through the sauce.
- Flour
- Helps thicken the milk-based sauce so it clings to the crab meat.
- Milk
- Forms the base of the sauce, giving it creaminess and a mild sweetness.
- Crab meat
- Provides the main flavor and tender, delicate texture of the dish.
- Sherry
- Adds aromatic acidity and depth at the end, brightening the rich sauce.
The step that matters
Gradually stirring the hot milk into the yolk mixture. Adding hot milk too quickly can scramble the egg yolks before the sauce thickens. Adding it slowly while stirring tempers the yolks so the sauce becomes smooth and creamy.
