642. Sprue-grass.—The longer the green part the better the sprue; take each piece and gently bend it, and it will break off at that part which you require, beyond it is too hard, and cannot be eaten; when you thus have the pieces, cut them into lengths of a quarter of an inch, which well wash; have one gallon of water, into which put one ounce of salt, and boil, then put in the sprue and boil for ten minutes, or till tender, then drain on a sieve, put them in a stewpan, with two ounces of fresh butter, half a teaspoonful of flour, the same of salt, two pinches of pepper, and place on the fire, stir well together, and serve hot. The yolk of an egg, well beaten with two spoonfuls of cream, may be added to it; and when serving, also two spoonfuls of white sauce or melted butter,—but I always do it as the first.
