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

What each ingredient does

Sugar
Provides sweetness and body, and helps the sauce thicken as it boils.
Chocolate
Supplies the chocolate flavour and richness that define the sauce.
Cream or milk
Adds moisture and creaminess, giving the sauce a smooth, pourable texture.
Butter
Adds fat for a glossy finish and a rounder, smoother mouthfeel.

The step that matters

Boiling for seven minutes while stirring constantly. Boiling with constant stirring keeps the sugar and dairy from scorching on the bottom of the pan. Sugar concentrates as water evaporates, so the sauce thickens; too little boiling leaves it thin, and too much makes it stiff once cooled.
