The proportion of gluten in different grades of wheat varies ; but the mere quantity of gluten is by no means the only standard of the commercial value of flour, the quality also counting for much. Soil and climate are essential factors in modifying the character of wheat, and necessarily of flour. The same variety of wheat, grown on the same soil, has also been known to show varying degrees of strength of its gluten in different seasons. Be this as it may, as a rule, wheat grown where the summers are short and not too hot furnishes the best and strongest gluten for bread making. For instance, the wheat grown in Russia is of the best. Canada wheat, like that grown in the Northern States, is ex- cellent, for the same reason. Wheat grown in the Middle States is 99 SCIENCE of FOOD and COOKERY of fair quality; but that grown in the Southern States and that grown in California, is usually soft, containing a weak gluten, and consequently not well adapted to the making of yeast-raised breads. Soft wheat is light-colored and has plump kernels; while hard wheat is commonly of a dark color, with kernels not so rounded as the former. Soft wheat is best for the making of crackers, pastries, and the like, as the dough is more brittle than that made from hard wheat flour. Hard wheat, when ground entire and made into bread, gives a dark-colored loaf with excellent flavor. If a good grade of flour is necessary for the making of satis- factory white bread, it is all the more needful in the making of entire wheat bread, as the mixture of bran particles in the flour permits the gas to escape a little more readily than when white flour is used, wholly or in part. In order to make good entire wheat bread, therefore, it is first of all essential to have a flour that contains a strong gluten ; also the flour must be ground fine, to prevent the gas from escaping before the dough is sufficiently light. The dough for entire wheat bread must be soft — so soft that it can scarcely be kneaded on the board. This is most important, because the bran absorbs moisture in the loaf, even after baking, and causes it to dry out. PRINCIPLES OF BREAD MAKING Breads are divided into -two classes : Fermented, made light by a ferment, yeast being usually em- ployed. Unfermented, made light by the introduction of air into the dough or batter. Fermented bread is generally made by mixing flour, water, salt, fat, and yeast to a dough, a small amount of sugar being added to hasten fermentation. The dough is kneaded until it is elastic to the touch and does not stick to the board, the object being to incorporate air, and to distribute the yeast' uniformly. It is then covered, and allowed to rise until it has doubled its bulk, and does not respond to the touch when tapped sharply, but gradually and stubbornly begins to sink. At this stage, the dough is "ripe," and ready to be worked down. It will require all the 100 SCIENCE of FOOD awf COOKERY
