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

What each ingredient does

Sugar
Provides sweetness and, as it concentrates while boiling, sets the final firmness of the candy.
Milk
Adds moisture and milk solids that give the caramel a creamy texture and mellow flavor.
Butter
Adds fat for richness and a softer, more tender bite in the finished caramel.

The step that matters

Continue boiling until the mixture begins to grain. Boiling drives off water and concentrates the sugar, so the stopping point sets how firm the caramels become as they cool. Watch for the stated graining, since overboiling or disturbing the mixture can cause sugar crystals to form unevenly.
