This is the best stuff ever. My kids think that they need to drink it.
1 1/2 Cup sugar
1 1/2 cube real butter (not margerine)
2 T Karo
3/4 cup buttermilk
Stir constantly while bringing to a boil on a medium heat. Once it starts to boil take of burner and add 1 tsp baking soda and 2 tsp vanilla. Stir well. It will foam up like caramel does just keep stirring and serve while it is still warm. It does start to separate a little as it cools but I always just reheat it if it does.
