A gravy is seasoned with nothing but salt and pepper, the object being to preserve the flavor of the meat. A sauce is highly seasoned to disguise poor meat, or made-over dishes, or whatever has been served so often that it begins to pall on the appetite.
An abundance of rich gravy is relished by campers who do not carry butter. They have nothing else to make their bread 11 slip down." Good gravy cannot be made from meat that has been fried properly or broiled, because the juice is left in the meat. Our pioneer families seldom had butter, yet they had to eat a much larger component of bread than we do, from lack of side dishes. Hence the " fried-to-a-chip " school of cookery.
In such case, the right way is obvious, granting that you have plenty of meat. Fry properly enough meat for the party and leave enough more in the pan to make gravy. Gash or mince this remainder, cook all the juice out of it without scorching, throw out the refuse meat, rub in a thickening prepared in advance as directed below, salt and pepper, then thin to the desired consistency with boil ing water. The thickening is made by rubbing cold milk, or water, or broth, a little at a time, into a spoonful of flour, until a smooth paste is formed, that will just drop from a spoon; or thicken with roux. Chopped liver improves a gravy.
Roux (pronounced "roo") is a thickening foi gravy or soups that can be prepared at any time and kept ready for emergencies. It will keep good for months in a covered jar. A teaspoonful thickens half a pint of gravy, or a pint of soup.
Brown roux is made thus: Melt slowly y2 lb. of butter, skim it well, let it stand for a minute to settle, and pour it off from the curd. Put the clear oily butter into a pan over a slow fire, shake into it enough sifted flour (7 or 8 oz.) to make a thick paste. Stir constantly and heat slowly and evenly until it is very thick and of a bright brown mlnr. Put it iato a jar. White roux is made in the same way except that it is stirred over a verj gentle fire until it is thoroughly baked but no\ browned. It is used for white gravy on fish, etc.
Some of the liquor in which the meat was cooked can be thickened by melting a piece of butter the size of a small egg, mixing with it very smoothly a tablespoonful of flour, heating until lightly browned, adding the meat liquor and letting it boil up. Flavor to taste and serve separately from the meat.
Use the drippings as above, and thin with boiling water in which half a teaspoonful of salt has been dissolved.
Drippmg is the fat that drops from meat when roasting.
When there is no venison in camp, it will not be long before the men crave the taste of beef. Liebig's extract, or Bovril, or Steero, dissolved in boiling water and liberally salted will make a good beef gravy by letting it boil up, then simmer, and thicken in one of the ways described above.
Rub up flour in water to a barer; salt it. Chop some onion very fine and fry it a little in the meat juice. Pour the batter on this, and stir till the flour is done.
1/2 pint milk. 1 tablespoonful butter. 1/2 tablespoonful flour. 1/2 tablespoonful salt. 1/8 tablespoonful pepper.
Heat butter in frying-pan. Add flour, stirring until smooth and frothy. Draw pan back and gradually stir in the milk. Then return the pan to the fire. Add salt and pepper. Stir until sauce boils. This must be used at once, and everybody's plate should be hot, of course.
A camp cook nearly always lacks the sweet herbs, fresh parsley, mushrooms, capers, anchovies, shrimps, tarragon, wine, and many other condiments to which standard sauces owe their characteristic flavors. He must make shift with spices and perhaps lemon, Worcestershire, vinegar, mustard, curry powder, or celery seed. How to use these to the best advantage cannot be taught in a book. Personal tastes and the materials at hand must govern. I give here the recipes for three simple sauces for meat. Others will be found in the chapters on Game, Fish, and Desserts.
Brown two teaspoonfuls of flour in a pan with a little butter. Put two table-spoonfuls of butter on a plate and blend with it the browned flour, a teaspoonful of mustard, and a little salt. When these are smoothly mixed stir them into pint boiling water. Simmer five minutes. Add enough vinegar or lemon juice to flavor.
Stir together one tablespoonful of butter with a teaspoonful of mustard and three tablespoonfuls of jelly (preferably currant). When these are well blended, add three tablespoonfuls of vinegar, some grated nutmeg, and a dash of Cayenne pepper. Heat together. When the sauce boils add three tablespoonfuls chopped pickles. Serve at once. Currant jelly alone goes well with venison.
Make the steak-dish very hot. Put on it for each pound of venison 1/2 tablespoonful of butter, a tablespoonful of currant jelly, one of boiling water, and a little pepper and salt. Turn the broiled steaks in the sauce once or twice and serve very hot.
I confess to a weakness for the flavor of parsley. The fresh herb, of course, we cannot have in camp, but the dehydrated kind, or C. & B. dried parsley, will do very well. Make a thin mixture of flour and water, salt it, and add a pat of butter (not really necessary). Boil this until the rawness is gone from the flour, and use it with fish, flesh, or fowl, particularly the latter.
