Coffee Test - Stir a teaspoon of ground coffee in a half glass of cold water; if coffee is good quality, it will who but little discoloration and very few grounds will sink to the bottom of the glass.
Another Coffee Test - Add a few drops of lemon juice to a glass of cold water; if pure, coffee will remain on top of the water; if not the water will at once change to brown color.
For a Good Cup of Coffee - put the ground coffee in a saucer and place it into a fairly hot oven for three minute before making; this will bring out the flavor.
When Making Coffee - always warm coffee-pot first; then sprinkle little salt on the coffee before pouring on the boiling water and the flavor will be greatly improved.
To Keep Coffee Pot Sweet & Clean - put a tablespoonful of bicarbonate of soda in it, nearly fill it with water and boil awhile; rinse in several lots of clear warm water.
To Keep The Best Coffee Urn Sweet - drop a small piece of charcoal in it, or a lump or two of sugar, and prop the lid open with a toothpick.
Instead of Using Cream - bring milk just to the boiling point and pour it steaming hot into the hot coffee, using enough to make it golden brown.
Darn... all I can think of now is an Grande Non-Fat Carmel Macchiatto from Starbucks.
