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 ↓
Butter 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 base
Combine sugar, water, molasses, butter, and vinegar in a saucepan.
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 and finish
Remove from heat and pour onto a buttered surface.
Let cool slightly, then pull and stretch until glossy.
Cut into pieces and enjoy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the firm, chewy candy structure as the syrup cooks and sets.
- Butter
- Adds fat for a rich flavour and a softer, less brittle bite.
- Vinegar
- Acid that helps prevent sugar crystals from forming, keeping the taffy smooth.
- Molasses
- Adds deeper colour and caramel-like flavour, plus a little extra sweetness.
The step that matters
Stop cooking at the hard ball stage. Sugar syrup sets according to its temperature. Stopping below the hard ball stage leaves taffy sticky and soft, while going too far makes it hard and brittle.
