Here's a scrumptious English Toffee recipe that I've made often. Don't ask about the number of calories though; you don't want to know! It's amazingly easy and a good gift for the holiday season:
1 pound butter
2 cups sugar
2 cups chopped almonds
12 oz. chocolate chips
1 cup finely chopped walnuts
Stir butter and sugar in large pan over high heat until melted.
Cook and stir constantly until toffee is very smooth and a medium to dark golden brown (about 10 minutes).
Add almonds and cook 1 minute longer. BE VERY CAREFUL NOT TO BURN IT!
Spread immediately in 13 X 9 X 2 buttered pan or on cookie sheet.
Cool 5 minutes and sprinkle chocolate chips on top.
As chips melt, smooth the surface with a spatula and then sprinkle chopped walnuts on top.
Cool in the fridge.
After toffee is solid, knock (I use a knife to pry it) from the pan and break into pieces.
