What each ingredient does

Sugar: Provides the bulk of the sweetness and forms the firm body of the caramel as it cooks.
Sweet cream: Adds fat and moisture, giving the caramel a soft, creamy texture.
Glucose: Interferes with sugar crystals forming, keeping the caramel smooth and chewy rather than grainy.

The step that matters

Cooking to 245°F (118°C). The final temperature sets the moisture left in the sugar mixture, which controls firmness. Stopping early leaves caramels soft and sticky; cooking too far makes them hard and brittle. Stir steadily so the mixture does not scorch on the bottom of the pot.
