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

What each ingredient does

Sugar
Adds sweetness and body to the sauce.
Cocoa
Provides the chocolate flavor and deep color.
Cornstarch
Thickens the sauce as it heats and bubbles.
Evaporated skim milk
Supplies the liquid that forms the creamy sauce base.

The step that matters

Cook and stir constantly until bubbly and thick. Cornstarch thickens only when it heats to a boil and its starch granules swell. Stirring prevents scorching on the pan bottom and lumps, and keeps the heat even so the sauce thickens smoothly.

Swap the cocoa

How well each one fits the dish's main ingredients (sugar, milk, vanilla):
