The best syrup you will ever eat. It's my favorite.
In a saucepan, bring butter, buttermilk, sugar, and Karo corn syrup to a boil.
Boil for 1 to 2 minutes.
Remove from heat, add baking soda and water. Stir to combine.
Add vanilla and stir to combine again.
Enjoy over pancakes, waffles and French toast.
