I got this recipe from my aunt, Ginger when she served it at our annual cousin (now 2nd cousin) sleepover. It is amazing! It's similar to the syrup at Kneeder's if you've been there.
1 cube butter
1 cup sugar
1/2 cup buttermilk (or regular milk with a 1/2 tbsp of vinegar mixed in. Let sit for a few minutes)
1 tsp Karo syrup
1 tsp baking soda
1 tsp vanilla
In a large pan bring first four ingredients to a boil stirring frequently. Remove from heat and stir in baking soda and vanilla. It will fizz. Serve hot!!
