What does bad cauliflower look like?

* Yellow or brown discoloration: This is a sign that the cauliflower is old and starting to spoil.

* Soft or mushy texture: Cauliflower should be firm to the touch. If it is soft or mushy, it is likely overripe.

* Black or brown spots: These are signs of mold or fungus.
