BURNT ONIONS FOR GRAVIES.
1130. INGREDIENTS.—1/2 lb. of onions, 1/3 pint of water, 1/2 lb. of moist sugar, 1/3 pint of vinegar.
Mode.—Peel and chop the onions fine, and put them into a stewpan (not tinned), with the water; let them boil for 5 minutes, then add the sugar, and simmer gently until the mixture becomes nearly black and throws out bubbles of smoke. Have ready the above proportion of boiling vinegar, strain the liquor gradually to it, and keep stirring with a wooden spoon until it is well incorporated. When cold, bottle for use.
Time.—Altogether, 1 hour.
PROPERTIES OF THE ONION.—The onion is possessed of a white, acrid, volatile oil, holding sulphur in solution, albumen, a good deal of uncrystallizable sugar and mucilage; phosphoric acid, both free and combined with lime; acetic acid, citrate of lime, and lignine. Of all the species of allium, the onion has the volatile principle in the greatest degree; and hence it is impossible to separate the scales of the root without the eyes being affected. The juice is sensibly acid, and is capable of being, by fermentation, converted into vinegar, and, mixed with water or the dregs of beer, yields, by distillation, an alcoholic liquor. Although used as a common esculent, onions are not suited to all stomachs; there are some who cannot eat them either fried or roasted, whilst others prefer them boiled, which is the best way of using them, as, by the process they then undergo, they are deprived of their essential oil. The pulp of roasted onions, with oil, forms an excellent anodyne and emollient poultice to suppurating tumours.
STEWED SPANISH ONIONS.
1131—INGREDIENTS.—5 or 6 Spanish onions, 1 pint of good broth or gravy.
Mode.—Peel the onions, taking care not to cut away too much of the tops or tails, or they would then fall to pieces; put them into a stewpan capable of holding them at the bottom without piling them one on the top of another; add the broth or gravy, and simmer very gently until the onions are perfectly tender. Dish them, pour the gravy round, and serve. Instead of using broth, Spanish onions may be stewed with a large piece of butter: they must be done very gradually over a slow fire or hot-plate, and will produce plenty of gravy.
Time.—To stew in gravy, 2 hours, or longer if very large.
Average cost.—medium-sized, 2d. each.
Sufficient for 6 or 7 persons.
Seasonable from September to January.
Note.—Stewed Spanish onions are a favourite accompaniment to roast shoulder of mutton.
ORIGIN OF THE ONION.—This vegetable is thought to have originally come from India, through Egypt, where it became an object of worship. Thence it was transmitted to Greece, thence to Italy, and ultimately it was distributed throughout Europe, in almost every part of which it has, from time immemorial, been cultivated. In warm climates it is found to be less acrid and much sweeter than in colder latitudes; and in Spain it is not at all unusual to see a peasant munching an onion, as an Englishman would an apple. Spanish onions, which are imported to this country during the winter months, are, when properly roasted, perfectly sweet, and equal to many preserves.
