Have ready boiling water; put into it a large handful of hops, and let them boil twenty minutes. Sift flour into a pan. Strain the liquor from the hops, and pour half of it over the flour. Let the other half of the liquid stand till it is cool, and then pour it gradually into the pan of flour, mixing it well. Stir yeast into it. Put it immediately into bottles, and cork it tightly. It will be fit for use in an hour. It will be much improved and keep longer, by putting into each bottle a tea-spoonful of pearl-ash.
