Eggs to Boil
The water must be boiling fast when the eggs are put in. First wipe them clean all over, with a wet cloth. It is true that the shells are never eaten, but still, if brought to table dirty and discolored, they look slovenly, disgusting, and vulgar, such as are never seen in good houses. Put them into water that is boiling fast; and if desired very soft, four minutes will be sufficient. Six or eight minutes will barely set the whites and yolks, and ten or twelve minutes (in water that is really boiling,) will render them hard enough for salad. In the egg-boilers that are set on the table no egg will ever boil hard, as the water cools too soon. A stale egg never boils hard.
Except in the spring, and late in the winter, there is often much difficulty in obtaining good eggs, unless you have fowls of your own. If an egg is really fresh, when held up against the light, the yolk looks round and compact and the white clear and transparent; you may then trust it. But if the yolk is thick, broken, and mixed among the white, and the white is cloudy and muddled, it is certainly bad, and should be thrown away. When tried in a pan of cold water the freshest will sink, and the stale ones float on the surface. It requires strong brine to bear up a good egg. Eggs may be preserved for keeping a few months, by putting every one in fast boiling water for one minute. Then grease them all over the outside with good melted fat, and wedge down close together (layer above layer,) in a box of powdered charcoal. This preserves them for a sea voyage of several weeks. The charcoal box must be kept closely covered, and closed immediately whenever opened. Pack the eggs with the small end downwards.
