Soft Molasses Taffy

Ingredients

Directions

Make the taffy base

  1. Combine molasses, glucose, butter, and burnt sugar color in a copper kettle.

  2. Stir and cook the mixture until it reaches a hard ball stage.

  3. Mix flour with a little molasses to form a paste. Add the paste to the kettle.

  4. Boil the mixture well.

Shape and finish

  1. Pour the mixture onto a greased marble surface.

  2. Fold in the edges as it cools.

  3. Add lemon oil.

  4. Pull the taffy over a hook until nearly cold.

  5. Stretch the taffy into flat bars of your desired size on the cold marble.

  6. Wrap the bars in wax paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Molasses
Provides the bulk of the sweetness and dark color, and a deep, slightly bitter flavor.
Glucose
Inhibits sugar crystallization, keeping the taffy smooth and chewy rather than grainy.
Butter
Adds fat that softens the texture and makes the taffy tender and less sticky.
Flour
Thickens the mixture slightly, giving the taffy body and a firmer, less brittle chew.

The step that matters

Pull the taffy until nearly cold. Pulling incorporates air and aligns the sugar structure while the mass is still pliable. Pulling too early or too late changes the final texture, so it is best done as the taffy cools.

Swap the lemon

Fit is the average pairing score against molasses, butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
