OYSTER SOUP.

Wash and drain two quarts of oysters, put them on with three quarts of
water, three onions chopped up, two or three slices of lean ham, pepper
and salt; boil it till reduced one-half, strain it through a sieve,
return the liquid into the pot, put in one quart of fresh oysters, boil
it till they are sufficiently done, and thicken the soup with four
spoonsful of flour, two gills of rich cream, and the yelks of six new
laid eggs beaten well; boil it a few minutes after the thickening is put
in. Take care that it does not curdle, and that the flour is not in
lumps; serve it up with the last oysters that were put in. If the
flavour of thyme be agreeable, you may put in a little, but take care
that it does not boil in it long enough to discolour the soup.
