These beans should be young, tender, and fresh gathered. Remove the strings with a knife, and take off both ends of the bean. Then cut them in two or three pieces only; for if split or cut very small, they become watery and lose much of their taste; and cannot be well drained. As you cut them, throw them into a pan of cold water, and let them lay awhile Boil them an hour and a half. They must be perfectly tender before you take them up. Then drain and press them well, season them with pepper, and mix into them a piece of butter.
