Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Adds deep flavor and cocoa fat that gives the caramel body and richness.
- Sugar
- Provides sweetness and, as it cooks, sets the candy firm when it cools.
- Butter
- Adds fat for a smooth, tender texture and a rich mouthfeel.
- Sweet milk
- Supplies moisture and milk solids for a creamy, chewy texture.
The step that matters
Boiling until it threads in cold water. The boiling point shows how much water has evaporated and how concentrated the sugar is. Boiling too little leaves the caramels soft and sticky, while boiling too long makes them hard and brittle once cooled.
