There is no great difficulty in making omelettes, and as they may be expeditiously prepared and served they are a convenient resource when an extra dish is required at short notice; care should be taken to beat the eggs only until they are light, to put the omelette into a well heated and buttered pan, and never to turn it in the pan, as this flattens and toughens it; if the pan be large, and only three or four-eggs be used in making the omelette, the pan should be tipped and held by the handle so that the eggs will cook in a small space upon one side of it; instead of spreading ail over it, and becoming too dry in the process of cooking.
There are three secrets in the making of a good omelette, namely, the separate beating of the eggs, the knack of stirring it upon the fire, and the method of transferring it from the fire to the table. If you will carefully follow the directions here given, you can produce a dish dainty enough to satisfy the most fastidious eater.
If you have to serve eight persons, make three omelettes as follows:
Put one half an ounce (about a tablespoonful) of butter into a clean, smooth frying-pan, and set it upon the back of the stove to melt; stir the yolks of three eggs with a saltspoonful of salt for one minute; beat the whites of three eggs to a stiff froth with an egg-whip, beginning slowly, and gradually increasing the speed until the froth will not leave the dish if it be turned bottom up; this will take from three to five minutes, according to the freshness of the eggs; now pour the yolks into the froth, and mix them gently with a silver spoon, turning the bowl of the spoon over and over, but do not stir in a circle, or rapidly; put the frying-pan containing the melted butter over the fire, pour in the omelette, and stir it with a large two-pronged fork (a carving fork will do), carefully raising the edges with the fork as fast as they cook, and turning them toward the centre, until the omelette lies in the middle of the pan in a light mass, cooked soft or hard to suit the taste; when done to the desired degree, turn it out upon a hot dish without touching it with either fork or spoon, and send it to the table immediately. Another excellent method is to beat three eggs, without separating the whites and yolks, with one tablespoonful of milk, and a little salt and pepper, and put them into a frying-pan containing two ounces of butter browned; let the omelette stand for a moment, and then turn the edges up gently with a fork, and shake the pan to prevent it burning or sticking at the bottom ; five minutes will fry it a delicate brown, and it should then be doubled and sent to the table at once on a hot dish. Three eggs will make an omelette large enough for two persons, if any other dish is to be served with it. There are several varieties of omelettes, each named after the ingredient prominent in the composition. We subjoin some excellent receipts, which may be based upon the first-mentioned method of preparation and cooking.
Stir into the yolks of three eggs a saltspoonful of salt, half a tea-spoonful of chopped parsley, one tablespoonful of chopped mushrooms, and one tablespoonful of shallot or white onion ; beat the whites of three eggs to a stiff froth, add them to the yolks, and cook as in the first receipt.
Use chopped or grated ham, or tongue, or cheese, in the proportion of one tablespoonful to one egg; proceed to mix and cook in the same way as for omelette with herbs.
Blanch one dozen small Blue Point oysters, by bringing them just to a boil in their own liquor, seasoned with a dust of cayenne, a saltspoonful of salt, and a grate of nutmeg; mix an omelette as above, omitting the herbs, place it over the fire, and when it begins to cook at the edges, place the oysters, without any liquor, in its centre, and fold and serve it in the same manner as the omelette with herbs.
Choose a dozen small, even sized mushrooms; if they are canned, simply warm them in the essence in which they are preserved, and if they are fresh, peel them by dipping them, held by the stem, into boiling water for one moment, and heat them over the fire with half an ounce of butter and half a saltspoonful of salt put over them ; prepare the omelette as above, and as soon as the edges begin to cook, place the mushrooms in the centre, and fold and serve like the omelette with herbs.
Peel two large ripe tomatoes, cut them in thin slices, put them into a frying pan with an ounce of butter, a saltspoonful of salt, and a dust of pepper, and toss them to prevent burning, until they are just cooked through; make an omelette as above, and as soon as its edges are cooked put in the tomatoes, and fold and serve the same as the omelette with herbs.
Heat a thick earthen plate over a charcoal or wood fire, until it will melt butter enough to cover the bottom of it, dust on the butter a little pepper, and sprinkle on a little salt; break into it as many eggs as will lay upon it without crowding, and brown them underneath; then set them where the heat of the fire will strike their tops, and let them color a pale yellow; salt them a little, and serve them very hot upon the same dish upon which they were cooked.
Prepare an omelette as directed in receipt No. 77, substituting any kind of jelly or preserves for the oysters.
