Have ready two quarts of very rich thick cream, and take out a pint. Stir gradually into the pint, a pound of the best loaf-sugar powdered fine; and the grated rind and the juice of four ripe lemons of the largest size, or of five or six smaller ones. If you cannot procure the fruit, you may flavour the cream with essence or oil of lemon; a tea-spoonful or more, according to its strength. The strongest and best essence of lemon is the white or whitish; when tinged with green, it is comparatively weak, having been diluted with water; if quite green, a large tea-spoonful will not communicate as much flavour as five or six drops of the white. After you have mixed the pint of cream with the sugar and lemon, beat it gradually and hard into the remaining cream, that is, the three pints. Cover it, and let it stand to infuse from half an hour to an hour. Then taste it, and if you think it necessary, stir in a little more lemon juice or a little more sugar. Strain it into the freezer through a fine strainer, (a tin one with small close holes is best,) to get rid of the grated lemon-peel, which if left in would prevent the cream from being smooth. Cover the freezer, and stand it in the ice cream tub, which should be filled with a mixture, in equal quantities, of coarse salt, and ice broken up as small as possible, that it may lie close and compact round the freezer, and thus add to its coldness. Snow, when it can be procured, is still better than ice to mix with the salt. It should be packed closely into the tub, and pressed down hard. While the cream is freezing, keep it always in motion, whirling the freezer round by the handle, and opening the lid frequently to stir and beat the cream, and to scrape it down from the sides with a long-handled tin spoon. Take care that no salt gets in, or the cream will be spoiled. When it is entirely frozen, take it out of the freezer and put it into your mould; set it again in the tub, (which must be filled with fresh ice and salt,) and leave it undisturbed till you want it for immediate use. This second freezing, however, should not continue longer than an hour, or the cream will become inconveniently and unpleasantly hard, and have much of the flavour frozen out of it. Place the mould in the ice tub, with the head downwards, and cover the tub with pieces of old carpet while the second freezing is going- on. When it has arrived at the proper consistence, and it is time to serve it up, dip a cloth in cold water, and wash it round the mould for a few moments, to loosen the cream and make it come out easily; setting the mould on a glass or china dish. If a pyramid or obelisk mould, lift it carefully off the top. If the mould or form represents doves, dolphins, lap-dogs, fruit baskets, etc. it will open down the middle, and must be taken off in that manner. Serve it up immediately lest it begin to melt. Send round sponge-cake with it, and wine or cordials immediately after.

If you have no moulds, but intend serving it up in a large bowl or in glasses, it must still be frozen twice over; otherwise it can have no smoothness, delicacy, or consistence, but will be rough and coarse, and feel in the mouth like broken icicles. The second freezing (if you have no mould) must be done in the freezer, which should be washed out, and set again in the tub with fresh ice and salt. Cover it closely and let the cream stand in it untouched, but not less than two hours. When you put it into glasses, heap it high on the top.

Begin to make ice cream about four or five hours before it is wanted for use. If you commence it too early, it may probably be injured by having to remain too long in the second freezing, as it must not be turned out till a few moments before it is served up. In damp weather it requires a longer time to freeze.

If cream is scarce, mix with it an equal quantity of rich milk, and then add, for each quart, two table-spoonfuls of powdered arrow-root rubbed smooth in a little cold milk. Orange ice cream is made in the same manner as lemon.
