Tomatoes.—(a) Cut up a number of tomatoes, and let them simmer gently in a stewpan over a slow fire until reduced to a pulp. From this squeeze all the juice by pressing it through a fine hair sieve; boil it until it thickens, and then pour it into small bottles. Stand these in a large fish-kettle or boiler, filling it with cold water, and putting some hay between the bottles and against the sides of the boiler, to prevent them from touching it or each other. Set the boiler on the fire, and let all boil for ¼ hour after the water comes to the boil. Let the bottles get cold in the water after taking the boiler off the fire. Then cork and seal them, and keep them in a dry place. Take care that none of the water gets into the bottles while boiling.
(b) If these are not to be packed for travelling, stone jars are better for their preservation than tins. Gather the tomatoes when perfectly ripe, and discard all that have blemishes. Pack them lightly till the jar is full, then entirely cover with strong vinegar and water in equal parts; add a few whole cloves and a sprinkling of sugar. Cover with a piece of flannel, letting it sink into the vinegar, then tie over with thick paper or bladder.
Truffles.—To keep truffles till required for use choose the blackest, let them be fresh gathered; when thoroughly washed and brushed, peel them carefully with a sharp knife, and reject all that are not perfectly sound; put them into bottles as close as they will lie, cork them tightly, and boil them for an hour in the bain-marie.
Vegetable Marrows.—(a) To preserve these for winter use, choose such as are fully ripe—turned yellow. When cut, arrange them in a dry place, resting on the flower end, with the stalk end upwards. They will then keep good the whole winter. (b) Cut them when fully grown, lay them on the pantry floor, and turn them twice a week, or put 2 pieces of tape or listing round them, and suspend them from a ceiling. The marrow improves in flavour, becoming quite nutty; they will keep in this way far into spring.
Walnuts.—(a) Walnuts intended for keeping should be suffered to fall of themselves from the trees, and be afterwards laid in a dry, open, and airy place, till they become thoroughly dried. Then pack them in jars, boxes, or casks, in alternate layers with fine clear sand, which has previously been well dried in the sun, in an oven, or before the fire; set them in a dry place, but not where it is too hot, and they will keep good till the latter end of April. Before they are sent to table wipe the sand off, and if they have become shrivelled steep them in milk and water for 6-8 hours; this will make them plump and fine, as well as cause them to peel easily. (b) Place them, fresh gathered and unwashed, in earthen jars, tied down with stiff glazed brown paper, and keep them on the floor of the wine-cellar. They are perfectly good until the new ones come in again, (c) Put the new walnuts in earthen jars with salt; cover them close, and leave them in a damp cellar. When you want to use them, wash them in cold water. At Christmas they will peel and eat like fresh fruit.
(c) Curing foods for lengthened preservation.
This branch of the subject may be conveniently divided into several sections, according to the means employed for rendering the foods less susceptible to change under the influence of the air. The most important agents are smoke and salt in the case of flesh, sugar for fruits, and vinegar for vegetables.
