Input:
I bought this yogurt maker because I wanted to make some dairy free yogurt using coconut milk rather than cow's milk. I am working on my second batch, and it seems to work fantastic. I have been using the 13.5 ounce cans of coconut milk. Right now I would say Native Forest brand is my favorite. I would discourage you from using the cartons in the dairy case, since these are not true coconut milk. I have been using plain Greek yogurt as the starter, but hope to locate a dairy-free plain yogurt starter. The coconut milk is firming up nicely into yogurt, but I am still in the experimental stage. Hope to update this as I progress.
