Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Extra Fine Caramel
Ingredients
Directions
Make the caramel
In a kettle, combine 4 cups of sugar and 3 cups of glucose.
Add 2 quarts of cream and stir well.
Cook the mixture until it reaches the soft ball stage.
Add 1 quart of cream and cook again until it reaches the soft ball stage.
Add another quart of cream and cook until it reaches the firm ball stage.
Flavor, set and cut
Remove from heat and flavor with vanilla and liquid chocolate or your chosen flavor.
Pour the mixture onto a surface between iron bars, about three-quarters of an inch thick.
Once cooled, cut into squares and wrap in wax paper.

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 cooks, the body and chewy texture of the caramel.
- Glucose
- Inhibits crystallization, keeping the caramel smooth and soft rather than grainy.
- Cream
- Adds fat and moisture, making the caramel rich and tender once it sets.
- Liquid chocolate
- Adds fat and chocolate flavor; it is stirred in off the heat to flavor the mixture.
The step that matters
Cooking to the soft and firm ball stages. Cooking time sets the sugar concentration, which determines how firm the set caramel will be. Stopping too early gives a soft, sticky result; cooking too far gives a hard, brittle one.
