How to Make Toffee
Making toffee at home means cooking butter and sugar (sometimes with a little water or corn syrup) to the hard-crack stage, about 149-154C / 300-310F, then pouring it out to set. A reliable candy thermometer, steady heat, and a heavy-bottomed pan are the main keys to success, and many recipes finish the slab with chocolate and chopped nuts.
The Basic Method
Combine butter and sugar over medium heat, stirring as the mixture melts, boils, and gradually darkens to amber. Cook until the syrup reaches the hard-crack stage (300-310F on a candy thermometer), then pour onto a lined sheet to cool and harden.
Temperature and Tools
Accuracy matters, since even a few degrees separate chewy from brittle toffee. A calibrated candy thermometer is the most reliable guide, though the cold-water test, dropping syrup into ice water to see if it forms hard, brittle threads, also indicates hard-crack.
