Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Molasses Taffy

Ingredients

Directions

Make the syrup

Combine molasses, sugar, vinegar, and water in a heavy saucepan over medium heat.
Cook the mixture to 255–270°F (124–132°C). The hotter the syrup, the harder the final taffy will be.
Remove the saucepan from heat and stir in butter, cream of tartar, and baking soda.

Pour and cool

Pour the mixture into a buttered pan or onto a marble surface, and let it cool slightly.
When the mixture is cool and thick enough to handle, grease your hands.

Pull and finish

Grab the candy mixture with both hands and stretch it apart while twisting slightly.
Repeat the pulling and twisting process until the candy is light in color.
Cut the taffy into 1-inch pieces and wrap each piece in squares of waxed paper.

What each ingredient does

Molasses: Adds deep flavor, dark color, and a chewy, sticky body to the taffy.
Granulated sugar: Provides sweetness and forms the crystal-free syrup base that sets into chewy candy.
Vinegar: Acidity helps keep the sugar from crystallizing, giving a smooth, pliable texture.
Butter: Adds fat that softens the texture and makes the taffy less brittle.
Cream of tartar: Acid that helps prevent sugar crystals from forming, keeping the candy smooth.
Baking soda: Reacts with the acidic syrup to create tiny bubbles that lighten the color and texture.

The step that matters

Cooking the syrup to 255–270°F (124–132°C). Temperature controls the final texture: the hotter the syrup, the more water has boiled off and the harder the taffy becomes. Undercooked syrup stays soft and sticky, while overcooked syrup turns brittle.
