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 ↓
Caramel Candy
Ingredients
Directions
Make the first candy
Combine 3 cups sugar, 1 cup milk, 1 cup chopped walnuts, and 1 tablespoon butter in a saucepan.
Caramelize 1 cup sugar, then add milk.
Let all the sugar dissolve, then add the other 2 cups sugar and butter.
Cook until it hardens in water.
Remove from the fire and add nuts.
Pour onto a buttered pan and cut into squares.
Make the second candy
Combine 2 cups granulated sugar, 2 tablespoons vinegar, 2 tablespoons butter, and enough water to moisten the sugar in a saucepan.
Cook until nearly done, which can be told by testing in cold water.
Add 1 cup grated chocolate and 2 teaspoons Royce's vanilla.
Pour into buttered pans.
While still warm, cut into squares with the back of a knife.
Make the third candy
Combine 2 tablespoons butter, 1 cup molasses, 2 cups brown sugar, 1 cup milk, 3 squares chocolate, and 1 teaspoon Royce's vanilla in a kettle.
Boil until, when tested in cold water, a firm ball may be formed in the fingers.
Add Royce's vanilla just after taking from the fire.
Pour into a buttered pan.
Cool and cut into small squares.
Make the fourth candy
Combine 1 cup molasses, 1 cup sugar, 1 cup butter, and 1 cup grated chocolate in a pot.
Boil until the mixture drops hard in water.
Combine 3 cups sugar, 1 cup molasses, 2 cups milk, 1 cup cake chocolate, and 1/4 cup butter.
Flavor with Royce's vanilla.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves and cooks into the firm or brittle candy structure as its syrup hardens.
- Butter
- Adds richness and a softer, smoother bite to the candy.
- Molasses
- Adds deep flavor and color, and moisture that keeps the candy chewy.
- Chocolate
- Adds chocolate flavor and dark color to the candy.
- Vinegar
- Its acidity helps keep the sugar from crystallizing into grainy candy.
- Brown sugar
- Adds caramel-like sweetness and depth of flavor.
The step that matters
Testing the sugar in cold water. Sugar syrup changes texture quickly as its temperature rises. Stopping too early leaves the candy sticky, while cooking too long makes it hard, grainy, or scorched.
