When I was young, there were wild white cauliflowers everywhere in the fields on the hillsides. At that time, I didn't know the deliciousness of this kind of vegetables. Maybe there was no shortage of farm vegetables in the countryside. I don’t know when people in towns started to eat this kind of wild vegetables. Maybe it’s because you have to go back to basics if you eat too much fish and meat! This kind of vegetable is cooked and cooled, and has the therapeutic effect of clearing heat. If it is truly wild, it will taste sweet and bitter. If it is artificially planted, it will only have a slight bitterness or even no taste.
