Eye-Water Recipe
June 5th, 2016
Cut a fresh hard-boiled egg into halves while hot, remove the yolk, fill the cavity with white vitriol, close the egg again, place in a vessel and cover tight to prevent the steam from escaping. Let it stand ten minutes, then take off the shell and strain the other part through a cloth. Add one teaspoon of sugar, one teaspoon of salt and a gill of rain water.
