Toffee
Toffee is a candy 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.
Creation
The process of making toffee requires the boiling of ingredients until the mix is stiff enough to be pulled into a shape which holds and has a glossy surface. The resulting mixture will typically be poured into a shallow tray and allowed to cool to form a slab. Different mixes, processes, and most importantly, temperatures, will result in different textures and hardnesses, from soft and often sticky to a hard, brittle material. A brown color, and smoky taste, is imparted to the toffee by the caramelization of the sugars.
Variants and applications
A popular variant in the US 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 type of candy 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 UK.
