I gave up doing a proper sit down starters good few years ago...too much faffing, too much food, too many extra dishes to wash.
Instead, we have delia smiths tiny savoury scones (google exactly that) topped with a variety of things like prawns, cream cheese, caviar, olives, just butter, handed round on a Christmasy plate and with a christmasy napkin each, and washed down with bucks fizz or just fizz, before we head into the dining room for the main event. They really get your taste buds tingling, much easier than a proper sit down starter.
