Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Condensed Sweetness Caramels
Ingredients
Directions
Make the caramel
Melt the butter in a kettle over medium heat.
Add the molasses and sugar, stirring until dissolved.
Let it cook undisturbed until nearly done, then stir constantly.
Boil until it becomes brittle in cold water.
Add the vinegar just before removing from heat.
Shape and cool
Pour into well buttered pans.
Pull with your fingers and thumbs, then cut with a sharp knife and place on buttered plates to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the bulk of the sweetness and the deep, dark flavor and color.
- Sugar
- Adds sweetness and helps the mixture harden into a brittle candy as it cooks.
- Butter
- Adds fat for a softer, richer bite and keeps the candy from sticking too hard.
- Vinegar
- Adds a little acidity that helps keep the sugar smooth and prevents crystallization.
The step that matters
Boil until brittle in cold water. Sugar candy sets by how far its water has boiled off. Undercooked caramel stays sticky and soft, while overcooked caramel turns hard or scorches, so checking the cold-water test matters.
