It's party time at Nigella's and this is one party that's full of fast, easy, delicious make-in-advance recipes and simple, achievable, last-minute touches to make the food table and the party itself ooze wow factor. With bite-sized potato cakes and smoked salmon, delicate crab and avocado wraps, easy-peasy red pepper and chickpea hummus, sticky sausages, and white chocolate mousses for dessert served in shot glasses. This is finger-lickingly good finger food.
