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

What each ingredient does

Sugar
Sweetens the squares and helps set the texture as the mixture boils.
Chocolate
Provides the main chocolate flavor and firm body once cooled.
Molasses
Adds dark sweetness and a deeper, slightly bitter flavor with moisture.
Milk
Adds moisture and creaminess to the mixture.
Butter
Adds fat for richness and a smooth, tender texture.

The step that matters

Boil the mixture for 20 minutes. Boiling drives off water and lets the sugar concentrate so the squares set firm when cooled. Too short a boil leaves them soft and sticky, while too long can make them hard or grainy.
