Cauli-cheese topped Potato Gratin

Description

A combination of two great classics, and outrageously indulgent side dish for serving alongside steak or roast beef - though makes a fine main course in its own right if accompanied by a sharply-dressed green salad and a few tomatoes.  

This dish is a bit of an oven-hogger, so either serve with something you can cook on the hob, or make the day before and simply return to the oven at 170°C for 30 minutes while your roast rests. If you do this, add the remaining cheese when you reheat rather than when you bake.
