Original Receipt in 'The Cook and Housekeeper's Dictionary' by Mary Eaton (Eaton 1822);VEGETABLE SOUP. Pare and slice five or six cucumbers, add the inside of as many cos-lettuces, a sprig or two of mint, two or three onions, some pepper and salt, a pint and a half of young peas, and a little parsley. Put these into a saucepan with half a pound of fresh butter, to stew in their own liquor half an hour, near a gentle fire. Pour on the vegetables two quarts of boiling water, and stew them two hours. Rub a little flour in a tea-cupful of water, boil it with the rest nearly twenty minutes, and serve it.
Another way. Peel and slice six large onions, six potatoes, six carrots, and four turnips; fry them in half a pound of butter, and pour on them four quarts of boiling water. Toast a crust of bread quite brown and hard, but do not burn it; add it to the above, with some celery, sweet herbs, white pepper, and salt. Stew it all together gently four hours, and strain it through a coarse cloth. Put in a sliced carrot, some celery, and a small turnip, and stew them in the soup. An anchovy, and a spoonful of ketchup, may be added if approved.
