Coffee may be made in various ways; by filtering, clarifying with an egg, or made with cold water. A common rule for making coffee is as follows: 1 heaping tbsp. ground coffee to 2 cups of freshly boiling water, 1 egg shell. Scald the coffee-pot, put in the coffee and the egg shell, add the boiling water, cover and boil just 3 minutes. Before serving, add a tbsp. of cold water; let stand for a few minutes before using.
