Take a peck of sorrel, separate the stalk from the eatable part, by taking hold of it with one hand and tearing off the rest with the other, so that only the stalk and fibres attached to it will remain after the tearing, and which you throw away. Wash it well, drain and set it on the fire in a saucepan with two tablespoonfuls of water; stir occasionally, and when nearly done, take off, mash through a colander, and it is ready for use.
