Graham and whole-wheat flour breads must be kneaded longer than white-flour bread, and require a hotter oven at first and a longer time for baking. Much Graham and whole-wheat bread is served insufficiently baked, probably owing to the fact that, being dark in color, the crust appears brown very soon, thus deluding the cook into supposing that the loaf is well baked. For thorough baking, from one to one and a half hours are needed, according to the size of the loaf and the heat of the oven. TOAST.--Toasting, if properly done, renders bread more digestible, the starch being converted into dextrine by the toasting process; but by the ordinary method of preparing toast, that of simply browning each side, only the surfaces of the slices are really toasted, while the action of the heat upon the interior of the slice, it is rendered exactly in the condition of new bread, and consequently quite as indigestible. If butter is added while the toast is hot, we have all the dyspepsia-producing elements of new bread and butter combined. Although considered to be the dish _par excellence_ for invalids, nothing could be more unwholesome than such toast. To properly toast the bread, the drying and browning should extend throughout the entire thickness of the slice. Bread may be thus toasted before an open fire, but the process would be such a lengthy and troublesome one, it is far better to secure the same results by browning the bread in a moderate oven. Such toast is sometimes called _zwieback_ (twice baked), and when prepared from good whole-wheat bread, is one of the most nourishing and digestible of foods. Directions for its preparation and use will be found in the chapter on "Breakfast Dishes." STEAMED BREAD.--Steaming stale bread is as open to objection as the surface toasting of bread, if steamed so as to be yielding and adhesive. It is not, perhaps, as unwholesome as new bread, but bread is best eaten in a condition dry and hard enough to require chewing, that its starch may be so changed by the action of the saliva as to be easily digested.
