Tagine is both the name of a dish and the name of the special clay pot that resembles a hat. Moroccans use it for almost all their main dishes.
This earthenware pot cooks food slowly and keeps meats and vegetables very moist to produce a kind of stew. The triangle shape is celebrated by Moroccans because it is reminds them of their belovedAtlas mountains. The hole at the top lets just enough steam to escape and evaporate some juices, but still maintain a right amount of liquid at the bottom to keep all the food moist.
