I stopped buying little yoghurt pots about two year ago. Having a small child who loved yoghurt meant we got through a lot. Even though I tried to reuse as many as I could most ended up being single use and filled up my plastic recycling bin. Instead I swapped to buying 1 large pot of yoghurt and decanting into smaller reusable tubs and pots when he needed one. Little baby pots are a perfect size for lunch boxes and when at home we just used a bowl. See the different in price in the picture. This is an eco-idea that is actually cheaper for once! Winning!
My next step is to have a go at making yoghurt in a slow cooker. Anyone tried it? We are holding a social online this afternoon.
