Water and fuel for cooking
Dry foodWater per kgCooking time
Rice1.5–2 L15–20 min (10 if soaked 30 min first)
Lentils3–3.5 L20 min, no soaking
Pasta3–4 L (reusable)10 min
Oats3 L soaked cold; 5–6 L cooked5 min, or soaked cold overnight with no gas
Corn flour (tortillas)1.2–1.5 LOn the griddle, 1 min each
Dried beans3 L + soaking60–90 min: the biggest gas user

With these amounts, the example household uses about 4 to 5 L of water a day just for cooking in weeks 2 to 5.

  • Stove: butane cartridge (227 g / 8 oz) or propane (1 lb cylinder), always outside, away from the building. A cartridge lasts 1 to 1.5 hours; cooking 40 minutes a day is 15 to 18 cartridges for 5 weeks: keep 20.
  • Retained-heat cooking: boil 3–5 minutes, turn it off and wrap the pot in towels or put it in a cooler for 45–60 minutes. It saves 50–70% of the gas for rice and lentils (hay-box cooking).
  • A 1 L thermos per person: one boil covers coffee, oatmeal and protein.
