Walnut Ketchup.
To three pints of the best white wine vinegar put nine Seville oranges peeled, and let them remain four months. Pound or bruise two hundred walnuts, just before they are fit for pickling; squeeze out two quarts of juice, and put it to the vinegar. Tie a quarter of a pound of mace, the same of cloves, and a quarter of a pound of shalot, in a muslin rag or bag; put this into the liquor; in about three weeks boil it gently till reduced one half, and when quite cold bottle it.
