Fermented Pineapple Soda with Vanilla Bean and Ginger + Tepache Margarita Author: Kelly Brisson Serves: 2L I made a batch of this with pureed pineapple and one with chunks of pineapple. I found the puree, of course, offered a stronger tropical flavour. Neither fermented better or worse, it was just a flavour thing. Feel free to do whichever you prefer.
