Wash clean some barley, (either pearl or common) and to two ounces
of barley allow a quart of water. Put it into a sauce-pan, adding,
if you choose, an equal quantity of stoned raisins; or some lemon-peel
and sugar; or some liquorice root cut up. Let it boil slowly
till the liquid is reduced one half. Then strain it off, and
sweeten it.
