Food Repair Guide: Baking Part 1

Bread

Bread, being about the first thing that man made, is also about the easiest. Ordinary bread is only flour, salt, liquid and yeast, well kneaded to mix, and baked. The modern cook with a food processor need not even bother about the kneading (which is only done to spread the yeast really thoroughly through the bread) as the food processor does it all for her. Unless, of course, she enjoys doing battle with balls of dough!

Ingredients/yeast

Flours differ but, as long as the flour is of good quality and dry, the differences are a matter of personal taste. Water is the normal mixing liquid and sea salt has a better flavour than table salt.

If the yeast is fresh and alive, when put in a damp, warm atmosphere, it will rise and grow whether it is incorporated in a dough or alone. Old age kills both compressed and dried yeast, as do extremes of temperature: anything over 110°F/50°C or below standard refrigerator temperature.

Once the yeast has been creamed by mixing it with sugar and a little warm liquid, it needs only to be thoroughly amalgamated into the dough, by hand or machine.

Rising, etc.

After the yeast has been mixed in, the dough must be left to rise, and in some cases prove. This will happen more or less quickly depending on the ambient temperature, but the longer it takes, the better the bread will be. Elizabeth David, among others, maintains that bread that has been left for 24 hours in a moderately warm kitchen will taste far better than bread that has been 'hurried' in a warming oven. However, an hour should be the minimum time — unless you are using a food processor and extra vitamin C to assist the raising.

If the dough does not rise, it means that the yeast is dead — whether through old age or overheating — and there is nothing you can do about it. Dead yeast has a smell and flavour not unlike dead cats and is totally unrevivable. Throw it out and start again.

Once you have mastered the basic techniques of bread making, all fancy breads are merely an elaboration on them. Most bakery books are extremely explicit in their instructions.

Cakes

Raising agents

Most cakes use eggs or chemical raising agents rather than yeast. The lighter sponges use whisked egg white; heavier sponges or fruit cakes use whole eggs or a combination of whole eggs and baking powder or bicarbonate of soda. These work by giving off gases when heated, thereby raising the mixture. The more chemical raising agent one uses, the lighter, dryer and less keeping the cake will be. Thus, fresh light sponges or angel cakes should be eaten within 24 hours to be at their best; a rich Madeira cake will keep several weeks; a fruit cake several months.

Mixing

The early mixing processes in all cake making are important, be it beating eggs and sugar to a ribbon or creaming butter and sugar for Victoria sponges. In both cases, early and thorough beating ensures that the cake will remain moist. Beating later in the process when the flour has been added will make the cake tough, heavy and elastic. Obviously, beating a light sponge after the egg white has been folded in would defeat the purpose of the operation.

For cakes that need to hold a filling in place — such as a cherry Madeira where you are attempting to keep the cherries in suspension — do not add all the liquid until you are sure that the full amount will not make the mixture too liquid to support the fruit.

Packet mixtures

If you feel that you cannot face the traumas of total cake making, there are a great number of excellent packet cake mixes on the market and you might be well advised to give up the whole business of being a home baker and use one of them.

Cooking

Follow the instructions in the recipe (or on the packet) for baking times and temperatures but do check yourself, as your oven may not behave exactly as the instructions say it should. Do not, however, continually open and shut the oven, as you will kill whatever chance the poor thing had of rising evenly in a constant heat. Similarly, when you test it, do not be too vigorous. If a light sponge gets a fat skewer stuck in it, it will break the crust and release half the air being carefully husbanded inside. Press the sponge very gently with your finger and, if it resists, it will be done. A more robust cake will stand the skewer treatment but, even then, do not do it more than you must.

Turning out

Whether the mixture is from a packet or home-made, it is most important that you are able to get it out of the tin when it is cooked. Greasing and flouring tins should work but has been known, only too often, not to — especially if the butter was salty! Invest in one, or several, loose-bottomed cake tins, which guarantee complete success — not only for cakes but for pâtés, mousses, jellies or anything else that you fear may lurk shyly in its container and refuse to emerge in public. If the mixture is very liquid, as in a very light sponge, line the tin with greaseproof paper to prevent it leaking out the bottom.

What Kind of Protein is Best?

There is a lot of confusion about "superior" and "inferior" proteins—so called "complete" and "incomplete" foods. At the beginning of the century, researchers doing animal experiments discovered that rats could live and grow on a single food such as eggs. Eggs, like meat, fish, and cheese, were therefore dubbed "complete" proteins. Vegetable foods such as rice, legumes, seeds, nuts, corn, and wheat were called "incomplete" since on their own they were unable to maintain life and growth. What all this meant is that the so-called "complete" proteins contain all the eight acids which humans cannot make for themselves in adequate amounts. But what they didn't take into account is that vegetable food—say, corn— together with another—say, red beans—also contains the eight essential amino acids and, provided you eat one vegetable together with another, you are getting the full complement of the eight essential amino acids in good balance. Better still, you are getting them without the fat that accompanies protein from animal foods. The idea that we need animal foods in order to be healthy is simply untrue. Populations numbering in the millions in different parts of the world have lived and developed enviable health and strength for thousands of years on a purely vegetable diet.

Diet Start

The best—and often the cheapest—sources of protein are the unrefined, unprocessed vegetable foods—complex carbohydrates complete with their natural fiber content, vitamins, and minerals—whole grains such as rice, wheat, oats, barley, legumes including lentils and beans; mixed seeds or mixed nuts; fruits, and vegetables from salad greens to carrots and potatoes. Eaten together in salads and casseroles, bread and soups, they provide low calorie menus without the danger of high fat from the intake of animal foods. The Lifestyle Diet provides 15 percent of your daily calories in the form of protein. It allows you to eat four ounces of meat, fish, or poultry (preferably fish) three times a week. On the days when you choose not to eat these foods you can have instead four ounces of mixed nuts or two eggs. It completely eliminates all cheese except those such as cottage cheese and curd cheeses made from low-fat milk.

If you prefer, you can take all your protein from vegetarian foods. The question of a vitamin B12 deficiency on a vegetarian diet is always brought up as evidence of the need to eat meat, although long ago biochemist Schweigert of the American Meat Institute researched the question and discovered that the need for B12 rises and falls with the amount of protein eaten. B12 is available in dairy products and eggs included in the Lifestyle Diet. In this kind of protein-economical diet it is correspondingly low. Schweigert also discovered that the whole wheat grain is a usable source of B12 provided it is not processed into white flour. If it had not been, then the millions of people in different countries who have lived almost exclusively on a vegan diet (vegetarian with no milk, dairy products, or eggs) would have suffered B12 deficiencies.
