1 hour ago, Tere said:sartoric, explain the greens and I will try to help? At a guess without more info some kind of spring cabbage? e.g. http://www.bbcgoodfood.com/glossary/spring-greens ?
Spring greens ! That's it. Thanks @Tere
They were usually just steamed or blanched and topped with butter.
We just don't get that variety of young cabbage here. It's probably not cold enough where we live to grow it ourselves. I might have to go back to London in the spring....
