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

What each ingredient does

Butter
Adds fat and richness, and melts into the sauce for a smooth, glossy finish.
Flour
Its starch thickens the hot sauce as the liquid heats and the starch swells.

The step that matters

Mix small portions of the butter paste into the hot thin sauce. Flour starch clumps when it meets hot liquid all at once. Adding the paste in small portions and stirring constantly lets each piece disperse and thicken evenly, which prevents lumps.
