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 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 taffy
In a large pot, combine the molasses, sugar, and butter.
Cook over medium heat, stirring constantly until the mixture reaches the hard ball stage (about 250°F or 121°C).
Remove from heat and let cool slightly.
Pull and shape
Once cool enough to handle, pull the taffy until it becomes light in color and texture.
Incorporate the peanuts into the taffy, then shape it into small pieces.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 chewy body of the taffy.
- Sugar
- Sweetens the taffy and, when cooked to hard ball stage, sets it firm once cooled.
- Butter
- Adds fat that softens the texture and keeps the taffy from sticking and turning brittle.
- Peanuts
- Add crunch and nutty flavor that contrast with the chewy taffy.
The step that matters
Cooking to the hard ball stage. Sugar syrup must reach the hard ball stage, about 250°F, so that once cooled the taffy sets firm yet chewy. Undercooked taffy stays sticky, while overcooked taffy becomes brittle.
Swap the peanut
How well each one fits the dish's main ingredients (molasses, sugar, butter):
- Almondfits better
- Pecansfits better
- Walnutfits about as well
- Peanutthe 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.
