The pots are lowered into the ground and cooked entirely by natural volcanic heat — around 100°C — with no added water; the steam pulls the juices out of the ingredients to make its own sauce.
Beef, pork, chicken, morcela sausage and vegetables are layered into a tall metal pot, sealed, and buried in geothermally heated volcanic soil near Lagoa das Furnas for several hours until fully cooked. Sold by the plate at market stalls and lakeside restaurants around Furnas.
