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
Make the taffy base
Combine water, glucose, dark molasses, and sugar in a large pot.
Stir until all ingredients are dissolved.
Wash down the sides of the pot and place a thermometer inside.
Cook and cool
Cover the pot and boil until the temperature reaches 265°F (130°C) in summer or 260°F (127°C) in winter.
Pour the mixture steadily onto a greased surface to cool.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Dark molasses
- Adds deep flavour and colour, and a dark, chewy texture to the taffy.
- Sugar
- Provides sweetness and, once cooked to temperature, sets the taffy's firm structure.
- Glucose
- Inhibits crystallisation so the taffy stays smooth rather than grainy.
- Water
- Dissolves the sugars so they can be cooked evenly into a syrup.
The step that matters
Boil to the target temperature. The final temperature controls how much water remains in the cooked syrup, which sets the taffy's firmness when cool. Undercooking leaves it soft and sticky; overcooking makes it hard and brittle. The lower target in winter reflects cooler, drier air affecting evaporation.
