Cauliflower can take a little longer to cook than broccoli. That’s why it’s important to make sure your florets are cut small and approximately the same size for even cooking time.

If your cauliflower is tough, it didn’t roast long enough. Pop it back in the oven for a few minutes and taste it again.
