Sorry if this is already known but, I have grown for the first time Turnip 'Oasis'(T&M) they have a fine ,delicate taste
when picked the size of a ping pong ball. I boiled a handful until tender then added a little unsalted butter a pinch of Malden
sea salt and a twist of pepper and whizzed until smoothish,and to my mind tasted as good if not better than traditional
bread sauce.
This jury is out on that one markfield. As a bread sauce afficianado, you can't make bread sauce with anything other than bread.
I'm afraid your recipe isn't so much 'mock' as 'muck'.

Bread sauce without bread - what is the world coming to!?! I would be lynched if I served that to my lot !!
