Salt and spices grow more slowly than the rest: doubling a dish does not double the pepper.

Weight converts to ounces and volume to cups. Grams of flour are not turned into cups, because that depends on how tightly it is packed.

About the dish

On the geothermal fields it is buried in hot sand by a spring for a full day. The home version is an oven at 100 °C for twelve hours, and the principle is the same: very long, very low heat.

The bread turns dark from the caramelisation of its sugars over those hours rather than from malt. It is the Maillard reaction alone, with nothing added for colour.

The tin is sealed tightly with foil. The steam inside prevents a crust forming, and the bread comes out moist and dense all the way through.

Worth knowing

  • Top up the water in the tray after six hours. Water boiled away means a dry oven, and the bread starts drying at the edges.
  • The tin has to be sealed completely. Any gap lets steam out and the bread comes out with a dry crust instead of a moist crumb.
  • The bread is cut very thin and served with salted butter and smoked lamb. A thick slice is too dense and too sweet.
