Buttermilk Syrup

I make this with homemade buttermilk pancakes.  It's divine.  It's good with German pancakes or waffles too.  

1 1/2 cups sugar

3/4 cups buttermilk

1/2 cup butter or margarine

2 Tbsp. corn syrup

1 tsp. baking soda

2 tsps. vanilla

Combine first 5 ingredients, bring to boil.  Boil 7 minutes.  Remove from heat and stir in vanilla.
