soups and gravies. Of these the principal are,--Scotch barley, pearl barley, wheat flour, oatmeal, bread-raspings, pease, beans, rice, vermicelli, macaroni, isinglass, potato-mucilage, mushroom or mushroom ketchup, champignons, parsnips, carrots, beetroot, turnips, garlic, shalots, and onions. Sliced onions, fried with butter and flour till they are browned, and then rubbed through a sieve, are excellent to heighten the colour and flavour of brown soups and sauces, and form the basis of many of the fine relishes furnished by the cook. The older and drier the onion, the stronger will be its flavour. Leeks, cucumber, or burnet vinegar; celery or celery-seed pounded. The latter, though equally strong, does not impart the delicate sweetness of the fresh vegetable; and when used as a substitute, its flavour should be corrected by the addition of a bit of sugar. Cress-seed, parsley, common thyme, lemon thyme, orange thyme, knotted marjoram, sage, mint, winter savoury, and basil. As fresh green basil is seldom to be procured, and its fine flavour is soon lost, the best way of preserving the extract is by pouring wine on the fresh leaves.
