I'm asking this for a friend who will be ordering Maf 878 from Dr. Enlander on ebay. He is having difficulty understanding the instructions. This instructions say: Use 1 gallon wide mouth glass jar add complete jar of STARTER KIT then add one pint of yoghurt one quart kefir one pint whole cream Keep mixture at approx 80 degrees F for five days before use. After 10 days keep mixture in refrigerator How do you keep a "glass jar" at exactly 80 degrees without a thermostat? What are you supposed to do with it for the 5 days between keeping it at 80 degrees and putting it in the fridge after 10 days? It seems he would need at least a gallon container (does it have to be glass??) with a thermostat at the very least. I read on this forum recently that Dr.Enlander rec's organic milk but i think maybe you or he meant cream or kefir? I want to send him my Yogoumet Multi yogurt maker to make this stuff but it heats up to 111-113F so that would be too warm I guess. Some are using heating pads? Do you wrap it around the jar? My friend is too sick to ask questions so if someone could please make it simple to understand because I can't offer any suggestions. Thanks.
