I have 11 sitting for Christmas lunch (plus another 8 arriving in the afternoon) so have decided to skip starter and go for champagne and canapes on arrival. Please would you be so kind as to tell me your favourite canapes - I do have a couple of ovens and a microwave but they will be largely in use that day so ideally something easy to prepare tasty (can be exotic) and the perfect ones could be prepared in advance. Thank you and Merry Christmas.
