Objective

By the end of this lesson, the student will learn the science behind making toffee, including the chemical reactions involved in candy making, and will successfully create their own batch of toffee.

Materials and Prep

• Granulated sugar
• Unsalted butter
• Water
• Salt
• Candy thermometer
• Heavy-bottomed saucepan
• Wooden spoon or heat-resistant spatula
• Baking sheet lined with parchment paper
• Optional: nuts or chocolate for topping

Before the lesson, ensure that all ingredients are measured out and ready to use. Discuss the importance of safety while cooking, especially when working with hot sugar mixtures.

Activities

• Introduction to Candy Science:

  Start with a brief discussion on what toffee is and the basic ingredients involved. Explain the role of each ingredient in the candy-making process.

• Making the Toffee:

  Guide the student through the steps of making toffee, emphasizing the importance of temperature control and constant stirring. Use the candy thermometer to monitor the sugar mixture until it reaches the hard crack stage.

• Tasting and Observing:

  Once the toffee is made and cooled, have a tasting session. Discuss the texture and flavor of the toffee, and encourage the student to describe their experience.

• Experimentation:

  Encourage the student to experiment with different additions such as chocolate or nuts. Discuss how these changes affect the flavor and texture of the final product.

Talking Points

• "Toffee is a type of candy made from sugar, butter, and water. The magic happens when we heat these ingredients!"
• "When sugar is heated, it melts and undergoes a chemical change. This is what gives toffee its unique flavor and texture."
• "The candy thermometer is our best friend in this process. It helps us know when the sugar reaches the right temperature for toffee."
• "When we stir the mixture, we help distribute the heat evenly, which prevents the sugar from burning."
• "Adding nuts or chocolate can change the taste and texture of our toffee. What do you think will happen if we add these ingredients?"
