The best and the easiest I've tried: Chop the almonds and pour them into a smallish (9" round) pan. Shake the pan so the almonds are spread evenly. In a heavy 2 quart saucepan, mix the butter and sugar over medium heat. Stir gently until the sugar is melted, then stir faster for about 5 minutes. Cook to hard crack stage. I usually know it's ready when the mixture forms i into one lump. Pour the sugar and butter onto the nuts and spread it evenly. Sprinkle the chocolate chips on top. Cover the pan. After about 5 minutes the chips will have melted, and you can spread them evewnly over the toffee. Cool and break into chunks. -sofia
