1, look at the color: Good cauliflower is generally white, milky white or yellowish, but cauliflower with a little yellow tastes better than white cauliflower. You can't buy cauliflower with dark color or black spots. This recipe is not fresh.

2, look at the flower ball: choose flowers seamless, strong and not yellow, the flower ball does not come loose, do not buy hollow stems.

3. Look at the leaves: cauliflower with green and full 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.
