The Oldest Cookbook in the World, clay Babylonian tablet, inscribed in Akkadian. It dates to ca. 1750 BC (the time of Hammurabi) and contains the oldest known cooking recipes.
This tablet includes 25 recipes for stews, 21 are meat stews and 4 are vegetable stews. The recipes list the ingredients and the order in which they should be added, but does not give measures or cooking time - they were clearly meant only for experienced chefs.
