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 ↓
Old-fashioned Molasses Candy
Ingredients
Directions
In a saucepan, combine molasses, brown sugar, and butter or lard.
Cook over low heat, stirring frequently, until the mixture is crisp and brittle when tested in a cup of water.
Add baking soda and nuts, stirring well.
Pour the mixture onto buttered pans and let it cool.

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, deep flavor, and sweetness that define the candy.
- Brown sugar
- Adds sweetness and helps the mixture harden into a brittle candy as it cooks.
- Butter or lard
- Adds fat that gives the candy a tender bite and smooths the texture.
- Baking soda
- Reacts with the hot syrup to release gas, making the candy light and brittle.
The step that matters
Cooking until brittle. The mixture must reach the crisp, brittle stage when tested in cold water. Stopping early leaves it sticky, while cooking too long can scorch the sugars and taste bitter. Low heat and frequent stirring help prevent burning.
Swap the nuts
How well each one fits the dish's main ingredients (molasses, sugar, butter):
- Almondfits better
- Pecansfits about as well
- Walnutfits about as well
- Nutsthe original
Fit is the average pairing score against molasses, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
