Make the base

  1. Combine glucose, sugar, Nucoa butter, butter, and cocoa butter with enough water to dissolve the mixture in a large pot.

  2. Cook the mixture over medium heat until it reaches 270°F to 280°F.

Pull and shape

  1. Pour the cooked mixture onto a slab.

  2. While pulling the taffy with a hook, gradually add the cream until fully incorporated.

  3. Flavor the taffy with vanilla.

  4. Pull the taffy into strips about four inches wide, cut into bars, and wrap them.

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

What each ingredient does

Glucose
Keeps the sugar from crystallizing, giving the taffy a smooth, chewy texture.
Sugar
Provides sweetness and forms the main structure of the candy as it cooks.
Butter
Adds richness and fat, softening the chew and contributing flavor.
Cream
Adds moisture and richness, making the pulled taffy softer and creamier.

The step that matters

Cooking to 270°F to 280°F. Cooking to this temperature range controls how much water remains in the sugar syrup. Too little cooking leaves the taffy soft and sticky, while overcooking makes it hard and brittle.
