One teaspoon of Malawi black in eight ounces of boiling water in a mug
infuser. Brew for 90 seconds, no more. (Square Peg may find that 88
seconds is better.) Take out the tea in infuser and brew in a second
mug (eight ounces) all morning or until you want it. Drink first
mugful when it's cool enough. Drink second mugful whenever you want.
The first mug should have most of the caffeine, and the second mug has
a crisp bitter/sour taste, like grapefruit. Toci
