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

What each ingredient does

Strong coffee
Provides the main liquid and the bold coffee flavour of the sauce.
Sugar
Adds sweetness and body, and helps separate the flour so it disperses.
Flour
Thickens the coffee as its starch swells in the hot liquid.
Thick cream
Adds richness, fat and a smooth, velvety texture to the sauce.

The step that matters

Stirring the flour and sugar into the boiling coffee. Flour clumps when it meets hot liquid. Mixing it with sugar first separates the particles, and stirring while pouring keeps the sauce smooth rather than lumpy.
