Potage à la Portugaise.—Fry 6oz. of minced
Portugal onions in 1½oz. of butter till well coloured,
then strew over them all a good spoonful of flour,
mix it well, and stir into it a teaspoonful of Liebig's
extract of beef, or a few drops of Maggi's essence,
season with a little celery salt and a dash of
coralline pepper, and pour on to it all nearly a quart
of stock, bring it slowly to the boil, skim well,
simmer it all for half an hour, sieve, and pour it
into a hot tureen, adding as you do so the yolk of
an egg beaten up and a spoonful of grated Parmesan
cheese.
