Walnut Soup

What with everything else both to eat and prepare over Christmas, elaborate first courses seem to be to be quite unnecessary. On the other hand, a good soup is a perfect start to a lunch or supper of cold turkey, meats or pâtés. Soups can, of course, be made ahead and re-heated very quickly, which makes them all the more practical for the Christmas period. This is an excellent, creamy winter soup of walnuts and soft, sweet onion that goes well with all Christmassy foods.
