To three pints of water put a small handful of hops, or if they are in compact pound papers, as put up by the Shakers, half a handful; boil them about half an hour. If the water wastes, add more. Put into the jar six or seven table-spoonfuls of flour, and a teaspoonful of salt. Set it near the kettle, and dip the hop tea, as it boils, into the jar through a small colander or sieve. When you have strained enough of the tea to wet all the flour, stir it, and let none remain dry at the bottom or sides of the jar; then strain upon it the remainder of the hop-water, and stir it well. This mixture should be about the consistency of batter for griddle-cakes. The reason for straining the hop-water while boiling is, that if the flour is not scalded, the yeast will soon become sour.
After it becomes cool (but not cold), stir in a gill of good yeast; set it in a slightly warm place, and not closely covered. Do not leave an iron spoon in it, as it will turn it a dark color, and make it unfit for use. When the yeast is fermented, put it in a cool place, covered close.
Yeast which is made in part of Graham flour rises light sooner than that which is made of white flour alone, and does not affect the color of the bread.
When yeast has a strong tart smell, and a watery appearance on the surface, it is too old for use.
