To the above lemonade or orangeade you add, instead of water and sugar,
some barley-water and sugar; it is very good and very refreshing.
Barley-water is made by soaking in lukewarm water a pint of barley,
drain it two or three minutes after; put the barley in a crockery pan,
cover it with cold water (about three quarts), set it on the fire, and
boil till the barley is perfectly cooked; skim off the scum during the
cooking, drain, let cool, and use the water.
