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

What each ingredient does

Butter
Enriches the roux with fat and carries flavour during the initial frying.
Flour
Thickens the stock into a smooth sauce once cooked in the butter.
Egg yolks
Emulsify the oil and vinegar, giving the dressing a thick, creamy body.
Cream
Adds richness and a smoother, silkier texture to the sauce.

The step that matters

Let the flour fry until golden before adding stock. Cooking the flour in butter removes its raw taste and lets it thicken evenly. Adding liquid too early can leave lumps and a floury flavour.

Swap the mustard

How well each one fits the dish's main ingredients (butter, flour, veal, cream, mushroom, egg, vinegar):
