Why it works: Butter and vinegar are a kitchen classic. They rank in the top 23% of all ingredient pairs, and cooks put them together in 13,513 recipes. Both carry isoamyl acetate, which smells banana, pear. The science ↓
For a Good Taffy Pull
Ingredients
Directions
Make the taffy
In a pot, combine molasses and butter.
Boil until thickened, about 30 minutes. Stir with a spoon.
Test by dropping a little taffy into cold water; it should harden.
Add vinegar and stir for 30 seconds.
Set
Pour the taffy into buttered tins or dishes and let it cool.

What each ingredient does
- Molasses
- Provides the bulk of the taffy and its dark color and deep sweetness.
- Butter
- Adds fat that keeps the taffy tender and smooth as it sets.
- Vinegar
- Adds acidity that helps prevent sugar crystals from forming, keeping the taffy soft and pullable.
The step that matters
Test the taffy in cold water. The mixture must reach the right concentration to set firm but still pull well. Dropping a sample into cold water shows whether it hardens, so you can tell when to stop boiling before it becomes too brittle or stays too soft.
