Ingredients

Directions

  2. Cook slowly over low heat until the mixture reaches 260°F (127°C) or hardens when dropped in cold water.

  3. Once cool, pull the taffy until it turns light brown.

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

What each ingredient does

Sugar
Provides the bulk of the sweetness and, as it cooks, the firm structure of the taffy.
Molasses
Adds deep flavor and a dark color, and keeps the taffy soft and chewy.
Butter
Adds fat for a tender, smooth texture and a rich flavor.
Glucose
Inhibits crystallization, keeping the taffy smooth and preventing grainy sugar.

The step that matters

Cooking to 260°F (127°C). The sugar concentration at this temperature determines whether the taffy sets firm and chewy rather than soft or brittle. Cooking slowly over low heat helps prevent scorching and uneven sugar concentration.
