If you are making buttermilk syrup, you are behind the times my friend. Of course you might be better off NOT making it, because it is NOT good for you. However, it sure tastes good! I had read lots of variations of how to make buttermilk syrup, but I just do it the simplest way possible. Once you start doing this, it is going to be hard to go back to Mrs. Butterworths.
1 stick butter
1/2 c butter milk
1 c sugar
1 t vanilla
2 t baking soda
Combine the first three ingredients in a sauce pan (use a fairly big one because it will boil high when you add the baking soda) and bring to a boil while stirring. Let boil for about 1 minute (you let it boil longer if you want a more amber, carmel taste, but I like it light). Turn off the heat then add the vanilla and baking soda. Stir and serve. And for heaven sakes, don't butter your french toast first, you have plenty of butter in your syrup!
You can play with it by using different flavors, cinnamon, nutmeg, almond extract, orange, lemon, rum . . . .the list is infinite!
