Chocolate Taffy

Ingredients

Directions

Make the taffy base

  1. In a kettle, combine glucose, sugar, and water. Stir until dissolved.

  2. Cook the mixture until it reaches 258°F (126°C).

  3. Remove from heat and add the chocolate, mixing well.

  4. Return to heat and bring to a boil again, then pour onto a greased slab.

Pull and shape

  1. After a few minutes, fold in the edges and knead until partly cool.

  2. Place on a hook and pull while adding vanilla flavor.

  3. Once well pulled, form into strips and cut into 5-cent bars.

    Shared aroma: guaiacol (smoky, sweet).

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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 crystallising, giving the taffy a smooth, chewy texture.
Sugar
Provides sweetness and, once cooked to temperature, the firm body of the taffy.
Bitter chocolate
Adds deep chocolate flavour and dark colour to the taffy.

The step that matters

Cooking to 258°F (126°C). The syrup must reach the target temperature to set the right balance of moisture and sugar concentration. Too little cooking leaves the taffy sticky and soft; too much makes it hard and brittle.
