Kale is even more heinous than rocket in my opinion...I guess it's like anything, some like stuff that others don't. I mean people love balut but it's not something you'll ever catch me eating it. Google will demonstrate what it is if you do not know.
I also don't like my hot food touching my cold food on a plate so...maybe I'm just weird.
Don't read too much into it mate, just a blog is all.
