I’ll have to try that. I use cola to control a chronic stomach problem (It works about 95% as well as the prescription I was taking, but is cheaper and with fewer side effects).
I’ve seen other cola recipes that called for fancy extracts or food-grade essential oils. I’ve been looking for one that used recognizable ingredients. This one looks promising.
It is very tasty. We didn’t go full strength on ours. We were afraid it would be too sweet. Add syrup to taste.
