Mumu is an earth oven from the highlands of Papua New Guinea. The term “mumu” encompasses both the oven and its layered feast, which is often prepared as part of a celebration. A mumu is a practical way to cook for a large party - it is dug into the ground (graun) to suit the available food (kaikai) or number of people (pipel). Heated stones are laid in the base of the hole and covered in a layer of large leaves followed by a layer of hard vegetables. Next is a layer of smaller, edible and aromatic leaves such as nasturtium then another layer of hot stones. The main ingredient - usually pig - is added, followed by more large leaves. Lastly it is covered completely with earth and left for several hours to steam before the contents are uncovered and presented ready for the feast.
