I got some kale from this place next to my job and it tastes like it was cooked in sugar and Yuck it's so nasty. Why would someone do that? I took a bite expecting a vinagary twang to it and instead it was sweet

It could be cooked with balsamic vinegar which is pretty sweet and actually has sugar added in the manufacture.
I like it steamed with a bit of butter (fake) and some toasted pine nuts.

No, I use balsamic vinegar when I cook them and it tasted nothing at all like that. It was so sweet I couldn't eat it. Nasty!

Molasses, I bet.

I used to put molasses and beer when I made collard greens.
