Before my uncle passed who made pottery in his shed with a wheel/kiln etc, he made me a large sauerkraut pot, which has a ceramic 2 piece weight to place on the cabbage and a lip on the edge to create a seal with water/oil. A traditional germanic design as he was based in Berlin for some time. I asked him if he would be able to make one as I was interested in all things to do with preserving food, and he gifted it me for the following Christmas. I treasure it in a way that surpasses anything bought in a store.
