It is very desirable that the gravy or sauce served with certain vegetarian dishes should be piquante in taste and of a nice flavour. It is worth while to take some trouble to achieve this result, because many dishes that are plain and perhaps somewhat tasteless in themselves are made quite savoury and enjoyable by the addition of a piquante dressing. Brand's A1 sauce is a good example of such piquancy, and is also useful in making sauces in the home, as a few teaspoons of it will often give an unique flavour to a simple gravy that is lacking in this respect. =157. Walnut Gravy.= Take about 4-ozs. of shelled walnuts, put them through the nut mill, and place in a small pan in which you have previously made hot 1-oz. of butter. Fry until the walnut is dark brown, _stirring well_ all the time to prevent burning. Pour on a pint of stock, or water if no stock is at hand, and let it simmer slowly until just before serving. Then add 1-oz. of flour to thicken, some seasoning, and a few drops of onion or some tomato sauce. This makes a most rich and savoury gravy--especially if a little nut-butter is added. =158. Curry Gravy.= In the cold weather, dishes which contain curry are seasonable and are generally appreciated. The following recipe for a curry gravy will prove useful to many readers, as it makes a capital addition to plain boiled rice or many other dishes. Fry 2 onions, minced in some butter until they are quite brown. Then sift in some flour and let it brown also. Add slowly some vegetable stock or water, two minced apples, a teaspoonful of curry paste (Stembridge's is good), a teaspoonful of vinegar, and a dessertspoonful each of tomato sauce and chutney. Stir and serve. =159. Gravy Piquante.= Stew a dozen shallots in some butter until soft. Stir in some flour and let it brown; add the juice of a lemon, 1/4-pint of water, a clove, a teaspoonful of sugar, and a pinch of salt and pepper. Boil gently for a few minutes and stir in a little more flour; add 1/2-pt. of clear stock or water, boil for 15 minutes and strain. =160. Plain Brown Gravy.= Melt some butter until brown, add flour (previously mixed well in a little water), and some vegetable stock, dilute if necessary and strain. A fried onion and tomato, and a teaspoonful of Nutter adds to the flavour and richness. The addition of Vegeton, Nutril or Marmite improves this. =161. Sauce Piquante.= Take equal quantities of vegetable stock and Tomate à la Vatel (Dandicolle and Gaudin), fry a chopped onion brown, add the above, thicken with arrowroot, boil and strain. =162. Rich Brown Gravy.= Melt 1 oz. butter or nutter in a small saucepan, then add nearly a tablespoonful of flour, and keep stirring until you get a rich dark brown, being careful not to burn; now add slowly some stock made by stewing brown haricot beans, and simmer slowly for about 20 minutes. At serving time, add a good teaspoonful of Nutril, Wintox or Marmite. =163. Tarragon Sauce.=
