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

What each ingredient does

Butter
Fat that combines with flour to form a roux, giving the sauce richness.
Flour
Thickens the sauce as its starch swells in the hot stock.
Hot stock
Liquid base that hydrates the flour and forms the body of the sauce.
Mushroom catsup
Adds savory, umami depth to the sauce.
Worcestershire sauce
Adds tangy, savory flavor that rounds out the sauce.

The step that matters

Gradually add the hot stock, stirring continuously. Adding liquid slowly while stirring keeps the flour dispersed, so lumps do not form and the sauce thickens smoothly as the starch swells.
