Onion Soup ‘Purée Alla Soubise.’ No. 2
Chop up a few onions, warm them in butter, but take care they do not brown. Stir in three tablespoonfuls of purée of white haricot beans, add a pinch of grated nutmeg, and rub through a sieve. If the purée is too thick add a little stock. Serve with croûtons (fried bread) in the soup.
