Lemon Catsup.

Grate the rind of the lemons; pound or grind the spices, and put all together, including the horse-radish. Strew the salt over all, add the lemon-juice, and let it stand three hours in a cool place. Boil in a porcelain kettle half an hour. Pour into a covered vessel—china or stone—and let it stand a fortnight, stirring well every day. Then strain, bottle, and seal.

It is a fine seasoning for fish sauces, fish soups, and game ragoûts.
