Yum. I have fermented cow’s milk, AKA yogurt, every night for dessert. Plain yogurt with some kind of fruit, blueberries and strawberries taste best.
I do sleep well and never miss things like ice cream. Sugar can keep you awake.
Try whole milk yogurt with a small amount of natural honey.
Good luck finding a yoghurt that doesn’t have a ton of sugar.
I had fermented camel milk in Kazakhstan. Tasted like yogurt.
