Recipe: Oyster Catchup

Take large salt Oysters that have just been opened. Wash them in their own liquor, and pound them, in a mortar, omitting the hard parts. To every pint of the pounded Oysters, add a half pint of white Wine or vinegar, in which you must give them a boil up, removing the scum as it rises. Then to each quart of the boiled Oysters allow a tea-spoonful of beaten white pepper, a salt-spoonful of pounded mace, and cayenne and salt to your taste. Let it boil up for a few minutes, and then pass it through a sieve into an earthen pan. When cold, put it into small bottles, filling them quite full, as it will not keep so well if there is a vacancy at the top. Dip the corks in melted rosin, and tie leather over each.
