Put a large cup of coarsely ground coffee shaken in and heaped up (4 ounces) into the perforated top of a coffee pot and pour over it 6 cups of boiling water. Keep the pot at boiling heat without actual boiling. When the water has run through, pour it off into another vessel and pour it through again and then once or twice more. Whatever sediment may have passed through in spite of the repeated filtering through the coarse coffee will remain at the bottom it never disturbed by boiling, and the coffee will pour off clear and strong. But very bad coffee is often made by careless people by this method.
