my partner made me buy a yogurt maker. I prefer the labor intensive method of warm oven in waterbath. I hate gadgets around the kitchen.

I make it every once in a while and for a starter use unflavored yogurt. It's the closest thing. I too like it puckery sour but my partner wants the sweet stuff.

Maybe time to make another batch some sweet and some sour... I like kefir. but for some strange reason, its hard to get myself to pour a glass of it.
