Make English toffee with almonds by melting butter in a heavy skillet over medium heat, stirring in sugar and water, and adding almonds before pouring the mixture onto a baking sheet. Alternately, add the almonds after pouring the mixture onto the baking sheet, along with chocolate flakes.
When making English toffee, it is important to cook the sugar, water and butter mixture until it becomes a dark amber color. If adding almonds before pouring out the mixture onto a baking sheet, make sure to add the almonds only after bringing the mixture to a boil; remove the mixture from heat once it reaches 285 degrees Fahrenheit. Additionally, chop the almonds into slivers for the best results, and cook them until they toast evenly. When adding sprinkles after pouring the mixture onto the baking sheet, using plastic gloves helps to minimize the amount of mess made. Aluminum foil can help keep the resulting toffee moist while cooling.
When letting the English toffee cool, either leave it out or place it in a refrigerator. Once it is cooled evenly, break it into pieces and store it in an airtight container. For the best results, use semisweet chocolate chips instead of sweeter, milk chocolate chips.
