To make Yeast.
Thicken two quarts of water, with fine flour about three spoonfuls; boil half an hour, sweeten with near half a pound of brown sugar; when near cold, put into it four spoonfuls of fresh yeast in a jug, shake it well together, and let stand one day to ferment near the fire, without being covered. There will be a thin liquor on the top, which must be poured off, shake the remainder, and cork it up for use. Take always four spoonfuls of the old to ferment the next quantity, keeping it always in succession.
An half peck loaf will require about a gill.
