“ When the skins crack in boiling, it is no proof that they are done, as too much fire under the pot will cause the skins of some potatoes to break while the inside is hard.After March, when potatoes are old, it is best to pare them before boiling and to cut out all the blemishes. It is then better to mash them always before they are sent to table. Mash them when quite hot, using a potato-beetle for the purpose; add to them a piece of fresh butter, and a little salt, and, if convenient, some milk, which will greatly improve them. ”
