Cauliflower Cake, Yotam Ottolenghi

This Lux version of Cauliflower Cheese, by Yotum Ottolenghi is adapted to TMX with slight changes to recipe and process. I made 1/2 recipe and this provides 3 or 4 serves depending on whether it is served as a main with salad or as a side dish.
The Cauliflower retains some texture and the light cheese  flavoured batter does not over power the cauliflower.
For the original recipe, please consult "Plenty More".
