Why did my cauliflower turn pink when cooked?

Online Answer
The culprit for this discoloration is oxidation, which happens naturally the longer cauliflower is stored. The good news is that you can still cook with this cauliflower. While the discoloration doesn't look appealing, it's harmless as long as the spots haven't turned a dark color or have a mushy texture.
