S SHALL BREAD BE KNEADED?--As the objects to be
attained in kneading dough are to render the gluten more elastic and
thoroughly to diffuse the yeast, it will be seen that there has been
sufficient kneading when all the flour necessary for the bread has been
added. Furthermore, it must be apparent that continued manipulation of
the dough at this stage will dissipate and press out the little vesicles
of gas held in place by the elastic gluten, and thus lose in part what
so much pains has been taken to secure. At whatever stage the requisite
amount of flour be added, the dough should then be thoroughly kneaded
once for all. If allowed to rise in bulk, when light it should be shaped
into loaves with the greatest care, handled lightly, and worked as
little as possible, and if at all diminished, allowed to rise again
before baking.
DRYNESS OF THE SURFACE.--Bread in all stages should be covered over
the top, since it rises much more evenly, and does not have a stiff,
dried surface, as when placed in a warm place exposed to air. It
sometimes happens that this precaution is forgotten or not sufficiently
attended to, and a dry crust forms and over the dough, which, if kneaded
into the loaves, leaves hard, dry spots in the bread. In case of such a
mishap, take the dry crust off, dissolve it in a little warm water, add
flour enough to mold, make it into a small loaf, and raise it
separately.
SIZE OF LOAVES.--The lightness of the bread after baking depends
upon the perfection with which the little air-cells, formed during the
fermenting process, have become fixed by the heat during the baking. The
heat expands the carbonic acid gas contained within the open spaces in
the dough, and at the same time checks further development of gas by
destroying the yeast plant. The sooner, then, that the cells can be made
permanent after the arrest of fermentation, the more light and porous
the bread will be. Although this fixing of the cells is largely
dependent upon the degree of heat maintained, it likewise in a measure
depends upon the size of the loaf, as the heat will penetrate and fix
the cells of a small loaf throughout much sooner than, those of a large
one. Therefore, bake in small loaves, and have a separate pan for each,
as that admits of an equal degree of heat to all sides. This aids in a
more rapid fixing of the air-cells and likewise gives more crust, which
is the sweetest and most digestible part of the bread.
