Just opened my yoghurt maker for the first time and was struck by the thought that before yoghurt makers, bread makers etc etc people would've had so many skills that we now don't have and feel we have to buy gadgets to do it for us. Like, I'm sure if I asked my Pakistani mother in law, she'd be able to tell me how to make yoghurt involving zero gadgets and very little time. So what other stuff along those lines is worth re-learning? Off the top of my head I can think of sprouting beans and seeds for bean sprouts, making bread without gadgets, repurposing old garments... Just wondering if anyone else had any ideas.
