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 ↓
Sour Cream Caramels
Ingredients
Directions
Make the caramel
Stir together sour cream, sugar, and grated chocolate until the sugar is nearly dissolved.
Cook over moderate heat, stirring gently once or twice to prevent scorching.
When a drop of syrup in ice water hardens quickly, add vanilla.
Pour and cut
Pour the candy carefully into a buttered pan.
When firm but not hard, remove from the pan and cut into small squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour cream
- Adds moisture and a tangy note, and makes the caramel softer and creamier.
- Sugar
- Provides sweetness and forms the candy's structure as the syrup cooks and sets.
- Grated chocolate
- Adds chocolate flavor, color, and fat that makes the candy rich.
The step that matters
Cooking to the right stage. The candy's firmness depends on how far the sugar syrup has cooked. Testing a drop in ice water shows when it hardens quickly. Cooking too little leaves the candy soft, while cooking too long makes it hard and brittle.
