A caustic compound, sodium hydroxide. Also known as soda lye or alkali. A very useful substance -- though it is no longer used regularly for making soap, it is used in making hominy grits, Drano, and oven cleaner.

If you see "Cocoa processed with alkali" on any chocolate product, rest assured that this means the cocoa has been reacted with lye.
