ISINGLASS AND GELATINE are used to make jellies, and thicken soups and gravies. Isinglass is made from the intestines of fish. Its advantages over gelatine are lighter color, less flavor, and greater thickening power. In cold water it softens, swells, becomes white and opaque. In hot water it smells a little fishy. Gelatine is made from the bones of animals; it also swells in cold water, but becomes glassy and transparent, while in hot water it has somewhat the smell of glue. It is often sold for isinglass. The test of both is in the fineness and clearness of their jelly. CALVES’ FOOT JELLY is delicate, but less firm. Gelatine is sold in sheets and shreds. HERBS for seasoning, as, SAGE, SUMMER SAVORY, SWEET MARJORAM, THYME, etc., are sold in the leaf, and also powdered, in tins and paper packets. Spices and Condiments. Spices are generally understood to be more aromatic and fragrant and less pungent than what are called condiments. Spices are usually added to sweetened food, while condiments, as pepper and mustard, are better suited to meats and food containing salt. It is impossible to supply genuine articles if the public are not willing to pay for them, and it may be accepted as a general rule, that the lower the price of ground spices and condiments, the more they are adulterated. The materials chiefly used for this purpose are starch, cracker dust and similar harmless substances, and the mixture usually contains as much of the pure material as can reasonably be afforded at the price it sells for. The purchaser may elect whether he will have such articles, or those which are genuine at a higher cost. The grocer does not create wants and demands; he merely supplies them. PEPPER.—There are two kinds, black and white. Both are from the seeds of the _piper nigrum_, a plant which grows in the East and West Indies. BLACK PEPPER is the seed picked before it is fully ripe, dried and ground. WHITE PEPPER is made from the ripened seed deprived of its black outer shell or pericarp. Pepper is an agreeable addition to many kinds of food, and is said to promote the secretion of the gastric juice; it is more used than any other spice. CAYENNE PEPPER is the powdered pod of one or more species of capsicum. The sharp taste is due to a camphor like substance found more in the pods than in the seeds. MUSTARD.—This is the flour of the black or white mustard seed. The black seed contains most volatile oil, is more pungent, and differs from the white in chemical composition. The two are blended in various proportions. Wheat flour is often added, with a little turmeric to bring up the color. Mustard seed contains over 30 per cent. of a fixed oil, and a portion of this is often extracted. This practice is considered beneficial rather than fraudulent.
