Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides the main sweetness and the deep molasses flavor of the caramel.
- Sweet milk
- Adds moisture and dissolves the sugar, giving the caramel a creamy, softer texture.
- Butter
- Adds fat for richness and a smooth, tender texture in the finished caramel.
The step that matters
Boiling without stirring. Stirring during boiling can cause sugar crystals to form, making the caramel grainy. Boiling until it reaches the hard-ball test stage sets the texture correctly, so the cook must watch the cold-water test closely.
