Jugging is the process of stewing whole animals, mainly game or fish, for an extended period in a tightly covered container such as a casserole or an earthenware jug.
In French, such a stew of a game animal thickened with the animal's blood is known as a civet
One common traditional dish that involves jugging is Jugged Hare (known as civet de lièvre in France), which is a whole hare, cut into pieces, marinated and cooked with red wine and juniper berries in a tall jug that stands in a pan of water. It is traditionally served with the hare's blood (or the blood is added right at the very end of the cooking process) and port wine.
