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 ↓
Molasses Chocolate Chips
Ingredients
Directions
Make the candy
Pour the vinegar over the grated chocolate and sugar; let it stand at room temperature to dissolve slowly without heating.
Once the sugar is melted, add it to the molasses and cook uncovered, stirring often until it spins a thread from the top of a spoon.
Stir in the butter and the baking soda dissolved in hot water.
Flavor with vanilla to taste and pour onto buttered platters to harden.
Set and cut
As it sets, cut into chips or bars with a buttered knife.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Forms the base of the candy and gives it its dark color and deep flavor.
- White sugar
- Adds sweetness and helps the candy set firm when cooked to a thread stage.
- Grated chocolate
- Adds chocolate flavor and richness to the candy.
- Vinegar
- Adds acidity that helps dissolve the sugar and keeps the candy from crystallizing.
- Baking soda
- Reacts with the acid to lighten the candy's texture as it is stirred in.
The step that matters
Cooking to the thread stage. Cook until the syrup spins a thread from a spoon. Stop too early and the candy stays soft; cook too long and it becomes hard and brittle. The stage controls the final texture.
