In the old days, they were called Hay Boxes. Before leaving the house to work in the fields, people would place the ingredients for lunch in a pot pre cook, then place in a box covered with hay and blankets to keep it cooking and warm for when they returned. The original slow cooker.

Nowadays, there are a lot of slow cookers on the market. But You can make your own custom cooker and yogurt maker. No electricity required!
