Look for Firm and Tightly Closed Heads

Cauliflowers are the parts in these vegetables, which are consumed. So, when purchasing cauliflowers, always look for tightly closed and firm heads as they are the indicators of freshness. The looser the heads, the staler they are and also do not taste good. Raw cauliflower is firm yet a bit spongy in texture. It has a slightly sulfurous and faintly bitter flavor.
