1494. Take, for 6 persons, the roes of 2 carp; [Footnote: An American writer says he has followed this recipe, substituting pike, shad, &c., in the place of carp, and can recommend all these also, with a quiet conscience. Any fish, indeed, may be used with success.] bleach them, by putting them, for 5 minutes, in boiling water slightly salted. Take a piece of fresh tunny about the size of a hen's egg, to which add a small shalot already chopped; hash up together the roe and the tunny, so as to mix them well, and throw the whole into a saucepan, with a sufficient quantity of very good butter: whip it up until the butter is melted! This constitutes the specialty of the omelet. Take a second piece of butter, à discrétion, mix it with parsley and herbs, place it in a long-shaped dish destined to receive the omelet; squeeze the juice of a lemon over it, and place it on hot embers. Beat up 12 eggs (the fresher the better); throw up the sauté of roe and tunny, stirring it so as to mix all well together; then make your omelet in the usual manner, endeavouring to turn it out long, thick, and soft. Spread it carefully on the dish prepared for it, and serve at once. This dish ought to be reserved for recherché déjeûners, or for assemblies where amateurs meet who know how to eat well; washed down with a good old wine, it will work wonders.
Note.—The roe and the tunny must be beaten up (sauté) without allowing them to boil, to prevent their hardening, which would prevent them mixing well with the eggs. Your dish should be hollowed towards the centre, to allow the gravy to concentrate, that it may be helped with a spoon. The dish ought to be slightly heated, otherwise the cold china will extract all the heat from the omelet.

GENERAL OBSERVATIONS ON PRESERVES, CONFECTIONARY, ICES, AND DESSERT DISHES.
PRESERVES.
1495. From the nature of vegetable substances, and chiefly from their not passing so rapidly into the putrescent state as animal bodies, the mode of preserving them is somewhat different, although the general principles are the same. All the means of preservation are put in practice occasionally for fruits and the various parts of vegetables, according to the nature of the species, the climate, the uses to which they are applied, &c. Some are dried, as nuts, raisins, sweet herbs, &c.; others are preserved by means of sugar, such as many fruits whose delicate juices would be lost by drying; some are preserved by means of vinegar, and chiefly used as condiments or pickles; a few also by salting, as French beans; while others are preserved in spirits. We have, however, in this place to treat of the best methods of preserving fruits. Fruit is a most important item in the economy of health; the epicurean can scarcely be said to have any luxuries without it; therefore, as it is so invaluable, when we cannot have it fresh, we must have it preserved. It has long been a desideratum to preserve fruits by some cheap method, yet by such as would keep them fit for the various culinary purposes, as making tarts and other similar dishes. The expense of preserving them with sugar is a serious objection; for, except the sugar is used in considerable quantities, the success is very uncertain. Sugar also overpowers and destroys the sub-acid taste so desirable in many fruits: these which are preserved in this manner are chiefly intended for the dessert. Fruits intended for preservation should be gathered in the morning, in dry weather, with the morning sun upon them, if possible; they will then have their fullest flavour, and keep in good condition longer than when gathered at any other time. Until fruit can be used, it should be placed in the dairy, an ice-house, or a refrigerator. In an icehouse it will remain fresh and plump for several days. Fruit gathered in wet or foggy weather will soon be mildewed, and be of no service for preserves.
1496. Having secured the first and most important contribution to the manufacture of preserves,—the fruit, the next consideration is the preparation of the syrup in which the fruit is to be suspended; and this requires much care. In the confectioner's art there is a great nicety in proportioning the degree of concentration of the syrup very exactly to each particular case; and they know this by signs, and express it by certain technical terms. But to distinguish these properly requires very great attention and considerable experience. The principal thing to be acquainted with is the fact, that, in proportion as the syrup is longer boiled, its water will become evaporated, and its consistency will be thicker. Great care must be taken in the management of the fire, that the syrup does not boil over, and that the boiling is not carried to such an extent as to burn the sugar.
1497. The first degree of consistency is called the thread, which is subdivided into the little and great thread. If you dip the finger into the syrup and apply it to the thumb, the tenacity of the syrup will, on separating the finger and thumb, afford a thread, which shortly breaks: this is the little thread. If the thread, from the greater tenacity, and, consequently, greater strength of the syrup, admits of a greater extension of the finger and thumb, it is called the great thread. There are half a dozen other terms and experiments for testing the various thickness of the boiling sugar towards the consistency called caramel; but that degree of sugar-boiling belongs to the confectioner. A solution of sugar prepared by dissolving two parts of double-refined sugar (the best sugar is the most economical for preserves) in one of water, and boiling this a little, affords a syrup of the right degree of strength, and which neither ferments nor crystallizes. This appears to be the degree called smooth by the confectioners, and is proper to be used for the purposes of preserves. The syrup employed should sometimes be clarified, which is done in the following manner:—Dissolve 2 lbs. of loaf sugar in a pint of water; add to this solution the white of an egg, and beat it well. Put the preserving-pan upon the fire with the solution; stir it with a wooden spatula, and, when it begins to swell and boil up, throw in some cold water or a little oil, to damp the boiling; for, as it rises suddenly, if it should boil over, it would take fire, being of a very inflammable nature. Let it boil up again; then take it off, and remove carefully the scum that has risen. Boil the solution again, throw in a little more cold water, remove the scum, and so on for three or four times successively; then strain it. It is considered to be sufficiently boiled when some taken up in a spoon pours out like oil.
