Why it works: Sugar and molasses 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 Taffy
Ingredients
Directions
The book gives no oven temperature. The 250°F in the steps was added when the recipe was transcribed, as a starting point.
Make the syrup
In a saucepan, combine sugar, molasses, butter, and vinegar.
Cook over medium heat, stirring until the sugar dissolves.
Continue cooking without stirring until the mixture reaches the hard ball stage (about 250°F or 121°C).
Shape the taffy
Remove from heat and pour onto a greased surface.
Let cool slightly, then pull and shape into taffy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sweet, firm candy base as it cooks to the hard ball stage.
- Molasses
- Adds deep flavor and color, and keeps the taffy soft and chewy.
- Butter
- Adds fat that makes the taffy tender and easier to pull.
- Vinegar
- Acid helps prevent sugar from crystallizing, keeping the texture smooth.
The step that matters
Cooking without stirring to the hard ball stage. Stirring once the syrup is hot can trigger sugar crystallization, making the taffy grainy. Reaching the correct temperature sets the firmness of the finished candy.
