YEAST.
Pare six good-sized potatoes; put them on to boil with three pints of water and a handful of hops; pour the water through a sieve on a pint of flour; stir it until perfectly smooth; mash your potatoes through a cullender into the yeast; stir all well together, and let it stand till nearly cold; then stir into it a pint bowl half full of dry yeast, dissolved in water; put the water on the dry yeast as soon as you mix your flour and potatoes, and when it has sufficiently cooled, your yeast will be ready to go in. Set it in a warm place to rise. When it is light enough, keep it in a cool place; cover it close. Yeast should be made the day before you bake; then it is good and fresh.
