A _Magnonnaise_ is a salad with alternate rows of cold fowl or roast veal, and lettuce, hard eggs cut in quarter slices, or carrot, or beet, gherkins, anchovy, &c. Cold potatoes cut in slices, and dressed with oil, vinegar, salt, and pepper, make an excellent salad, which may be varied by the addition of fine herbs, slices of beet-root, or anchovies taken from the bones and chopped fine. _Boulettes_ of cold meat, chopped small, and mixed with crumbs of bread or mashed potatoes, are also very useful _impromptu_ dishes. The mixed meat and bread or potatoes is seasoned with pepper, salt, a little parsley, and other herbs, and a shallot or two cut very small; the yolk of an egg or two is then added, and the mixture is made into balls, which are just glazed over with white of egg, and then fried; after which they are served with a little gravy or sauce of any kind, or covered with parsley put before the fire till it is quite crisp. Cold potatoes may also be cut in slices and warmed in a casserole, with some butter mixed first in a plate with a little flour, some parsley cut very fine, pepper and salt, and a very little lemon-juice or vinegar: this is called _à la maître d'hôtel_. They may also be cut in slices and fried, and then served with _sauce blanche_. _Sauce blanche_ is made by mixing butter with some flour on a plate, and then putting it into a casserole with a little water. It should be held over the fire, and frequently shaken, till it boils; it is then taken off the fire, and a little salt and vinegar thrown in; after which it is again shaken, and held over the fire till it is quite hot, but not boiling, when it is served. Some cooks add a little of the yolk of eggs, well beaten up with the salt and vinegar. _Carrots_ are very good boiled, and then cut in slices, and dressed _à la maître d'hôtel_, or fried and served with _sauce blanche_ like potatoes. Carrots are also very good cut into small pieces and stewed till they are tender, with a little butter, and only just enough water or gravy to prevent them from burning. A sauce is made of the yolk of an egg beaten up with some cream, a little salt being added, and it is poured on the carrots; the saucepan is then again put on the fire, and when the whole is quite hot it is served. It may be useful here to mention two or three kinds of sauce which may be used either for cold meat or fish; and also some of the ways the French have of dressing cold fowl or veal, which are very nice. _Dutch sour sauce._ Take the yolks of two eggs, a lump of butter, a little bit of mace, and a table-spoonful of good white-wine vinegar. Put all together into a saucepan over a gentle fire, and keep stirring all one way till the sauce is thick enough for use.
