Baked Potatoes
For baked potatoes, select those which are of uniform size and not very large. Scrub them thoroughly in a stream of water from the faucet, to wash off every particle of sand, for many like to eat the outside. Bake them in a hot oven for from forty-five to fifty minutes. If the potatoes are of medium size, and do not cook in that time, it indicates that the oven is not of the proper temperature.
Baked potatoes, not being exposed to the solvent action of a liquid, lose none of their potash salts in cooking, as boiled potatoes do. The same is true of those roasted, and of those fried raw in deep fat.
