This. Is. Amazing! So, I thought I'd do a test run of this drink as Halloween is a couple of days away and would have some of the butterscotch leftover to use on Halloween. Big mistake. I took one swig and fell madly in love. As did DH.... long story short... we have no butterscotch left. And I dare not make any more until the day it's being served :) The ginger beer/cream soda combo is great alone, but swirl in that gorgeous butterscotch and dollop on the lovely scotch-y cream... Heaven! I used all light brown sugar and subbed an extra tsp of corn syrup for the molasses as I had none. I also used scotch in place of the vinegar.
