Brown sugar or sugar-candy to taste. Half an ounce of liquorice.
Put the linseed and water in a pan and boil for ten minutes. Then strain off the water into a jug, add to it the lemons, cut in thin slices, the sugar - or, better still, crushed sugar-candy - to taste, and the liquorice broken into small pieces.
This drink is very refreshing and good for coughs and colds.
Note. If the flavour of liquorice is objected to, it may be omitted.
