If it is fish, vegetables, flour, etc., you can use cooking skills to make finished dishes. Of course, not everything can be cooked. Go check the recipe information online. Different ingredients can be used to make different dishes. Of course, there are certain requirements for cooking skills. There is also barley and wheat that need to be ground into powder in a windmill before cooking.

(I think your family does not cook wheat directly.) If it is "food waste"...throw it away...(cooking failure, that is, the raw materials cannot be combined into finished dishes or the ratio of raw materials is wrong, and fishing will get food waste)< /p>
