Some months ago, I started making yoghurt, as the yoghurt here isn’t much to my taste. Except for 1 brand, all the yoghurt is sweetened. And “the good stuff” both isn’t great and is often sold out (no surprise, I think to myself…). So I found a yoghurt maker (that was a surprise) and got started. I let it stew in the pots for a very long time, and it comes out fairly tart.
I’ve changed my technique since these pictures were taken in May: now I put a half a teaspoon of my starter yoghurt into each pot, and disolve the rest into the milk before filling the pots.
