Toffee is a confection made by caramelizing sugar or molasses (creating inverted sugar) along with butter, and occasionally flour. The mixture is heated until its temperature reaches the hard crack stage of 149 to 154 °C (300 to 310 °F). While being prepared, toffee is sometimes mixed with nuts or raisins.
A popular variant in the United States is English toffee, which is a very buttery toffee often made with almonds. It is available in both chewy and hard versions. Heath bars are a brand of confection made with an English toffee core. Although named English toffee, it bears little resemblance to the wide range of confectionery known as toffee currently available in the United Kingdom. However, one can still find this product in the UK under the name “butter crunch”.
