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 ↓
Molasses Candy
Ingredients
Directions
Make the candy
Combine molasses, brown sugar, vinegar, and melted butter in a saucepan.
Boil the mixture without stirring for about 25 minutes, until it hardens when dropped into cold water.
Add baking soda and stir just enough to mix.
Pour immediately into shallow, well-buttered tins and let it harden.
Optional pulling
Optionally, pull the candy by dipping your hands in ice water or melted butter during the process.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the dark color, rich flavor, and sweetness that define the candy.
- Brown sugar
- Adds sweetness and helps the mixture set into a firm candy when boiled.
- Vinegar
- Adds a small amount of acidity that works with the baking soda in the candy.
- Baking soda
- Reacts with the hot syrup to release gas, making the candy light and porous.
- Butter
- Adds richness and a smooth texture to the finished candy.
The step that matters
Adding the baking soda. Stir only enough to mix. The baking soda reacts quickly with the hot syrup and releases gas, so pour the candy into the tins immediately before the bubbles subside and the candy loses its lightness.
