| | FoodTale: SALT |
 | | Sea water is evaporated, and rock salt is mined--so important is salt for the flavor of food, the needs of the diet, and even digestion (by increasing the hydrochloric acid content of digestive fluids). |
 | | Salt is the only rock directly consumed by man. It corrodes but preserves, dessicates but is wrested from the water. |
 | | Its trans-Saharan trade, for example, began on the Mediterranean coast, where salt was dried in salt pans, and went by caravan, oasis to oasis, along the Sahara desert to southern forests--returning with gold dust, ivory, goat skins, and slaves. |
