Buy a red cabbage, some vinegar and salt and some peppercorns. Chop the cabbage, mix the vinegar with water and the salt. Put it all in a clean jar. Wait 2 weeks. Eat.
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.
Yeah man, it encourages me to make things for people. Having a craft skill is so useful for those around you. My dad was a joint and woodturner, my aunt does quilting and textiles and another knitted amazing sweaters for my kids with their names on etc they have made so many cool things for people over the year, it's never too late to learn a new skill, my dad took up tap dancing at 65
