Wow! That looks like a type of broccoli I grew back in the 80's. It was supposed to look that way. I googled it. It said it is usually eaten raw. I googled broccoli. You might want to google Romanesco cauliflower.

Cool

It looks like Romanesco except that's usually more lime green. I think the distorted area is just a bit of fasciation - pretty common in brassicas. We eat quite a bit of it but not raw in particular. I just use it any way I'd use cauliflower or broccoli . I prefer the flavour to either white cauliflower or green broccoli. If you're really keen on it you can get the matching lampshade!
