I want to make yoghurt with my frozen but freshly thawed out raw goat milk. I want to use Redwoodhill store bought goat yoghurt as a starter. I don't have a yoghurt maker... anyone have instructions for how to do this? It doesn't matter if it doesn't come out thick, because I'm going to make a drink out of it anyway. I just don't want it to to become something other than yoghurt, and I would like to keep the benefit of the rawness, if possible. TIA!
