Sour powder is the perfect option for one person to eat, to cook with a small milk pot, to cook directly with a pot, and to bring to the table a bowl less, you lazy evangelical. As for the groceries, who doesn't have a scab stock at home, a friend who eats alone, advises me not to lose a piece of pork in the fridge, and I'll make up for it. It's no trouble to buy sour sauerkrauts, so just bring two vegetables at the after-school shop, or even cook them in the office, cook them in the dormitory, which is certainly better than takeout。
