If the rain is lashing the windows, a voluptuous, comforting root gratin should be on your menu. This does well either as a side dish or a weeknight meal in its own right.
Heat the oven to 180°C/Gas 4 and grease a gratin dish or shallow ovenproof dish with a knob of butter.
Put the cream, milk, bay leaf and garlic into a pan with a generous seasoning of salt and pepper. Slowly bring to a simmer then turn off the heat and leave to steep for 10 minute
