Klah, a coffee-esk drink in most fantasy works. Originally found in the books of Pern (a hot, stimulating drink made from tree bark and tasting faintly of cinnamon." - The Dragonriders of Pern). There is a entry about it in the A Dash of Salt Sub.
The name and basic drink has been adapted by many authors, both science fiction and fantasy. It has become something of an in-joke among the writers. Klah is always a hot beverage, most often with a coffee-esk taste with some other enhancement. Most often it is a chocolate taste, but other essences are sometimes used.
It is frequently used in an Arth Submission http://www.strolen.com/view.php?node=free_search&free=Arth
The original is here, but on Arth…
To an Earthworlder, this drink has a coffee chocolate taste. It provides a caffine buzz (and since it is often served with honey… a sugar buzz as well). It is normally served in ceramic mugs. This product is mostly the product of Amarian Farmers (who strangely enough do not drink Klah, just eat Klah candies and baked goods). Mostly this is the City Drink of Antioch, but has been found in MaskLand (who have gone insane over the drink), and various parts of SecondLand.
Klah berry bushes are a finicky plant to grown. The small berries (1.1cm) and (huge) pits (1 cm) are crushed into a soft paste. The oils are saved for other confectionary applications. The paste, once dried, is then ground to a fine powder and kept in air tight tins or waxcloth bags.
This powder can be added straight to hot water (though in honesty, it is usually with a touch of honey or beet sugar), or hot milk (with honey mostly for children) or a mix of hot water and milk (usually with honey/ sugar and other spice). A person’s preference for Klah can be an unique as their fingerprints.
While Klah can be made at home, most people get it from a favorite "cart" or foodshop.
