The nicest way to make sponge cake, or diet-bread, is the weight
of six eggs in sugar, the weight of four eggs in flour, a little
rose-water. The whites and yolks should be beaten thoroughly and
separately. The eggs and sugar should be well beaten together; but
after the flour is sprinkled, it should not be stirred a moment longer
than is necessary to mix it well; it should be poured into the pan,
and got into the oven with all possible expedition. Twenty minutes is
about long enough to bake. Not to be put in till some other articles
have taken off the first few minutes of furious heat.
