Interesting. So instead of spinach a la creme it’s kale a la creme. I figure it works better with frozen kale than fresh, as it will have a finer structure.
The Dutch do one thing very well and that’s winter food. Probably similar in Danmark, as fellow Northsea coast dwellers.
Here in the Netherlands you can pay practically everywhere electronically (even the door to door collectors for charities carry a qrcode in addition to their collection box) , but if you go next door to Germany you’d better bring cash if you want to buy anything.
