It is Christmas, and Nigella is having a fabulous easy drinks party. On the menu there are meltingly tender turkey meatballs in tomato sauce and a must-have party recipe, wholegrain mustard, and ginger cocktail sausages served in a scooped-out loaf. For something a little different, there is gorgeous grilled halloumi in radicchio leaves with a zingy beetroot and lime sauce. Then as festive a dessert as you could imagine, squares of black beer gingerbread with snow-white icing sugar. For a final flourish, a simple, seasonal cocktail, Filthy Fizz.
