(Directions for Cookery, 1851)
Take a gallon of stale strong beer, a pound of anchovies washed from the pickle, a pound of peeled shalots or small onions, half an ounce of mace, half an ounce of cloves, a quarter of an ounce of whole pepper, three or four large pieces of ginger, and two quarts of large mushroom-flaps rubbed to pieces.
Put the whole into a kettle closely covered, and let it simmer slowly till reduced to one half.
Then strain it through a flannel bag, and let it stand till quite cold before you bottle it. Have small bottles and fill them quite full of the catchup. Dip the corks in melted rosin,
This catchup keeps well at sea, and may be carried into any part of the world. A spoonful of it mixed in melted batter will make a fine fish sauce. It may also be used to flavour gravy.
