Mix 1 cup sugar with 2 Tablespoons cornstarch in a saucepan.
Mix well and add 2 cups boiling water. Boil 5 minutes. Add 1 Tablespoon butter and 1 teaspoon vanilla. Add a pinch of salt.
(Lemon flavoring may be used instead of vanilla)
Serve warm over warm peach cobbler
This is a lot so I usually only make 1/2 a recipe.
