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
In a saucepan, combine the molasses, sugar, and butter.
Boil the mixture without stirring until it forms hairs or becomes brittle in cold water.
Once done, quickly stir in the baking soda.
Pour and stretch
Pour the mixture into buttered pans.
When cool enough, stretch the candy well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the main flavor and dark color, and its sugars help the candy set chewy.
- Granulated sugar
- Adds sweetness and helps the boiled mixture reach a firm, brittle set.
- Baking soda
- Reacts with the hot syrup to release gas, making the candy light and porous.
The step that matters
Boil without stirring, then add baking soda quickly. Stirring during boiling can cause crystals to form, leaving the candy grainy. Hot syrup needs to reach the correct stage, and adding baking soda quickly keeps the gas bubbles evenly distributed for a light texture.
Swap the walnut
How well each one fits the dish's main ingredients (molasses, sugar, butter):
- Almondfits better
- Pecansfits about as well
- Walnutthe original
- Chestnutfits about as well
Fit is the average pairing score against molasses, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
