why does Romanesque cauliflower turn reddish?

Asked October 23, 2014, 9:32 PM EDT

I like to buy times Romanesque cauliflower at the farmer's market. When I buy it it is bright green, but as it sits in the fridge, and especially after it is on the counter for a while and I have started to cut it, it starts to change color, turning reddish and sometimes starting to get a deflated appearance.I don't remember this happening in past years. Any ideas what causes this? Is it normal? Is there a way to prevent it?

Thanks for using the Ask an Expert System,

I cannot find anything in the literature that matches the condition you describe. One source mentioned that romanesco cauliflower will keep in the refrigerator for 2 to 3 days. After that it will start getting soft and turn brown. I would guess that freshness is very important and that oxidation could account for the color change. You should make sure that the produce you buy is freshly picked, and then store in sealed containers in the refrigerator. If you purchase more than a 2 day supply you can freeze romanesco cauliflower.
