Cooking : Butterscotch Bars I

Ingredients
3 cups zwieback cracker crumbs
2 cups miniature marshmallows
1 cup chopped pecans
2/3 cup packed brown sugar

In a large bowl combine zwieback crumbs, marshmallows, nuts and brown sugar.
In a saucepan over low heat cook the evaporated milk and butterscotch chips. Stir mixture constantly until the chips have melted and the mixture is smooth. Reserve 1/2 cup of the butterscotch mixture for glaze. Combine the remainder with the dry mixture and mix well.
