Hmmm I am not sure if i've ever tasted these my friend! But I am so happy to discover 'grelos' thanks to you! This is what I wanted to see with this special round of SIC!
The bitter taste you are explaining makes me think of the wild mustard greens that we usually enjoy a little bit same as yours!
Lovely entry as usual and thanks so much for the little story behind it!
Steem on!
