FISH SOUPS.—(No. 225.)
Eel Soup.
To make a tureenful, take a couple of middling-sized onions, cut them in half, and cross your knife over them two or three times; put two ounces of butter into a stew-pan[208] when it is melted, put in the onions, stir them about till they are lightly browned; cut into pieces three pounds of unskinned eels, put them into your stew-pan, and shake them over the fire for five minutes; then add three quarts of boiling water, and when they come to a boil, take the scum off very clean; then put in a quarter of an ounce of the green leaves (not dried) of winter savoury, the same of lemon thyme, and twice the quantity of parsley, two drachms of allspice, the same of black pepper; cover it close, and let it boil gently for two hours; then strain it off, and skim it very clean. To thicken it, put three ounces of butter into a clean stew-pan; when it is melted, stir in as much flour as will make it of a stiff paste, then add the liquor by degrees; let it simmer for ten minutes, and pass it through a sieve; then put your soup on in a clean stew-pan, and have ready some little square pieces of fish fried of a nice light brown, either eels, soles, plaice, or skate will do; the fried fish should be added about ten minutes before the soup is served up. Forcemeat balls (Nos. 375, 378, &c.) are sometimes added.
Obs. Excellent fish soups may be made with a cod’s skull, or skate, or flounders, &c. boiled in no more water than will just cover them, and the liquor thickened with oatmeal, &c.
