Tried this as an option for Keto friendly yoghurt. I mix milk&cream to have lower carb yoghurt. need a thermometer, i added the starter into the milk when it was too hot once, and it didnt work. but the rest of the time, lovely yoghurt. i also use milk powder so i can make more anytime. Takes a little bit of time to make - heat in pot instructions. And i just pop it in a coolerbag with a hotwater bottle overnight.
But totally worth the effort. almost finished my first box, about to order more.
