1, the optimum storage temperature of vegetables is 0℃, which can be stored for about 3-4 weeks, and the humidity should be kept above 95%rh. Cauliflower is wrapped with plastic wrap, which loses less water, but if the storage temperature is slightly higher, the surface is prone to black mold. Therefore, when stored at a higher temperature, those without plastic wrap are better than those with plastic wrap. But when stored at low temperature, the storage quality of non-plastic wrap is far worse than that of plastic wrap, because it loses more water.

2. Good cauliflower is generally white, milky white, or yellowish, but cauliflower with a little yellow tastes better than white. You can't buy cauliflower with dark color or black spots. This recipe is not fresh. Broccoli with full green leaves is fresher. The leaves are yellow or wilting, indicating that they are not fresh. In addition, be careful not to have too many leaves, otherwise it will take up weight.
