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

What each ingredient does

Grated chocolate
Melts into the liquid to give the sauce its rich chocolate flavor and body.
Corn starch
Thickens the sauce as it boils, giving it a smooth, pourable body.
Sugar
Adds sweetness and helps give the sauce a smooth, glossy texture.
Milk
Adds creaminess and softness to the chocolate sauce.

The step that matters

Boil for five minutes, stirring constantly. Cornstarch must reach a boil to fully thicken, and constant stirring prevents lumps and scorching on the bottom of the pan.
