Place one level tablespoon of medium finely ground coffee in the pot for every cup desired; add the water and bring quickly to the boiling point. Stir with a spoon and then add a small pinch of salt and four tablespoons of cold water to settle the grounds. Let it stand in a warm place for five minutes; then serve.
Place three-quarters of a level tablespoon of finely ground coffee in a percolator for each cup desired. Add the water and then place the pot on the fire. Let the coffee filter just four minutes after the first pumping of the water in the glass top shows a coffee color. This will produce an even, uniform cup of stimulating beverage.
