Beat egg whites to peaks

Put sugar, karo, water and salt in a saucepan. Mix slightly but do not stir. Cook until, when dropped in a bowl of cold water, the mixture becomes solid but not brittle. (265 degrees on a candy thermometer)

Immediately pour mixture into beaten egg whites, add vanilla (and food coloring, optional), and beat until mixture can be dropped onto wax paper with a spoon and remain solid.
