Toffee— Store bought or homemade?
You can use either store bought or homemade toffee. Making toffee is a simple process that requires just 3 ingredients—butter (1 stick) , brown sugar (1 cup), and 1 tablespoon of salt. To begin, melt the butter, sugar, and salt down together in a saucepan over medium heat. Be sure to stir the mixture constantly to ensure it doesn’t separate. As the ingredients melt and combine, the mixture will gradually darken in color, transforming into a rich golden brown. Continue to heat until the toffee reaches a temperature of 300F (150C), use a candy thermometer to check temp. Immediately pour the toffee onto a baking sheet lined with parchment paper into a thin, even layer. The toffee will harden as it cools then can be broken into bits.
