Favorite Buttermilk Syrup

This is just a slightly different recipe from the other Buttermilk syrup on this blog, but I think I like it a little bit better.  The other one sometimes doesn't work out for me.  If you have that problem, too, give this one a try!

1 stick butter

1 1/2 cups sugar

3/4 cup buttermilk

2 Tbs corn syrup

1 tsp vanilla

1 tsp baking soda

Melt butter in a 4 qt pot over stove, add other ingredients except baking soda.  Turn on medium high and bring to a bubble of a boil, then add soda.  Remove from heat.
