To the remainder add 300 g (11 oz) small Croutons of bread fried in butter and 1 litre (1¾ pt or 4½ U.S. cups) White Bouillon; finish cooking together gently. Pound, pass through a fine sieve, adjust the consistency with 2½ dl (9 fl oz or 1⅛ U.S. cups) boiling milk, then pass again through a fine strainer.
