FOR CAPTAINS OF SHIPS
To make Catchup to keep twenty Years.
Take a gallon of strong stale beer, one pound of anchovies washed from the pickle, a pound of shalots peeled, half an ounce of mace, half an ounce of cloves, a quarter of an ounce of whole pepper, three or four large races of ginger, two quarts of the large mushroom-flaps rubbed to pieces; cover all this close, and let it simmer till it is half wasted, then strain it through a flannel bag; let it stand till it is quite cold, then bottle it. You may carry it to the Indies. A spoonful of this is to a pound of fresh butter melted makes a fine fish-sauce, or in the room of gravy sauce. The stronger and staler the beer is, the better the catchup will be.
