To boil potatoes properly much care and judgment are required. They should be peeled thinly, and well washed in cold water, but not soaked; put them into a saucepan kept for this vegetable only. Just cover them with cold water seasoned with salt, and bring to a boil. Then simmer very gently for about twenty minutes; test them with a fork, and if soft, strain off the water and toss them in a saucepan over the fire until they are dry. Some potatoes will not bear boiling as long as this, but begin to break soon after they boil up. When this is the case, pour off nearly all the water, leaving only one inch at the bottom of the saucepan. Cook the potatoes slowly in this and then strain off and dry. Potatoes that are very troublesome to boil often steam well; they must be allowed from an hour to one hour and a half, according to the quantity of water over which they are cooking.
