We will be out visiting our families for much of Christmas Day so I like to spend Boxing Day morning playing with the children and looking at all their new things etc. But I will be catering for 12 later in the day and decided that rather than a buffet I would do sausage and mash with roast veg and Nigella's cumin, onion and red wine gravy followed by some yummy puddings.
BUT.... I don't want to spend all Boxing Day peeling potatoes. Can I make the mash beforehand? Should I fridge or freeze? What is the best way to reheat? Could I put it in casserole dishes and grate some cheese on top and stick it in the oven? Would it heat through OK that way?
