Blinis (pre-made for convenience) topped with smoked salmon, sour cream, half quail egg and caviar
Vol-au-vents (pre-made for convenience) filled with one of the following:
Horseradish, rare roast beef, topped with crispy onion & beetroot
Smoked mackerel mousse topped with cucumber and dill
German grain bread cut into bite size squares, topped with Brie/Cambazola or Gorgonzola/Stilton, with cranberry sauce or a fig (or other) chutney
Serve as canapés about an hour before dinner - this means you get to relax and have a glass or two as well, then leave everyone to chill while you get back to cooking. I like this approach because you don’t need to stress if dinner takes longer as no one will be starving.
Or you could do one huge baked Camembert or several smaller ones for sharing, with crusty bread, breadsticks, olives, antipasti, charcuterie, cranberries and walnuts, and whatever other accompaniments you fancy.
