Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Molasses Taffy
Ingredients
Directions
Make the syrup
In a saucepan, combine brown sugar, molasses, and water.
Boil until a drop in cold water forms a soft ball that you can pick up with your fingers.
Add butter and continue cooking until the candy is brittle when tested in cold water.
Stir in vanilla extract.
Shape the taffy
Pour the mixture onto buttered pans and pull it to shape.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides the main sweetness and body of the taffy as it cooks down to a syrup.
- Molasses
- Adds deep flavor and color, and keeps the candy softer and chewier.
- Butter
- Adds fat that gives the taffy a smoother, richer texture.
- Cream of tartar
- Adds acidity that helps prevent sugar from crystallizing, giving a lighter texture.
The step that matters
Avoid stirring once boiling. Stirring a boiling sugar syrup can encourage sugar crystals to form, which makes the taffy grainy instead of smooth. Letting it boil undisturbed keeps the syrup clear and the texture even.
