This is the recipe my Mom has made for years.

3c sugar
1/2c light corn syrup
1/2c water
2 egg whites room tempurature
1tsp vanilla
2/3 c walnuts

place sugar, cornsyrup, and water in a heavy saucepan, cook and stir over medium heat untill sugar is dissolved. continue heating mixture without stirring untill it reaches the soft ball stage, 240 degress on a candy thermomater. meanwhile using an electric mixer beat egg whites untill stiff. pour half of syrup mixture into egg whites;beat while pouring. return remaning syrup to continue cooking untill it reaches the brittle stage,300 on thermametor. pour slowly into egg whites. continue beating mixture untill it reaches a non glossy stage when dropped with a spoon untill it holds soft peaks. if too stiff for mixer use a spoon for final beating. add vanilla and nuts pour into a buttered pan.
note; also yummy with raisins in it.
