Complete Primitive Cooking Methods: From Open Fire to Earth Oven
Cooking without modern equipment requires understanding heat transfer, fire management, and improvised cooking vessels. This campaign covers open fire cooking, earth ovens, hot rock cooking, and food preparation.

Coal bed cooking: 1) Build large fire and let burn to coals (30-60 minutes). 2) Spread coals into even bed (2-3 inches deep). 3) Place grill (green wood rack) 4-6 inches above coals. 4) Cook food on grill (similar to modern grilling). 5) Control heat: raise/lower grill, spread/concentrate coals. 6) Add fresh coals from fire as needed. 7) For ash roasting: bury food directly in hot ash and coals. 8) Wrap food in leaves (banana, grape, corn husk) to protect from ash. 9) Root vegetables: 30-60 minutes buried in coals. 10) Meat: wrap in clay for clay-baked cooking (seals in moisture).
Chapter 2: Earth Oven (Underground Oven)
Earth oven construction: 1) Dig pit 2-3 ft deep, 3-4 ft diameter. 2) Line bottom with rocks (river rocks, NOT wet rocks from streams, they can explode). 3) Build large fire in pit on top of rocks. 4) Burn for 2-3 hours (rocks must be extremely hot). 5) Remove fire and excess ash (leave hot rocks). 6) Place layer of green vegetation (grass, leaves) on hot rocks. 7) Place food on vegetation layer. 8) Cover food with more green vegetation. 9) Optional: add water to create steam (speeds cooking). 10) Cover with earth (seal completely, no steam escaping). 11) Cook for 4-12 hours depending on food quantity. 12) Uncover carefully, remove food. 13) Result: slow-cooked, tender, smoky food.

Stone boiling: 1) Heat rocks in fire until glowing (30-60 minutes). 2) Fill container with water and food (bark basket, animal stomach, wooden bowl). 3) Use wooden tongs or split stick to transfer hot rocks to water. 4) Rocks instantly heat water (one fist-sized rock raises 1 quart significantly). 5) Add rocks until water boils. 6) Remove cooled rocks, add fresh hot ones to maintain boil. 7) Continue until food is cooked. 8) This method allows boiling in ANY container that holds water. 9) Even a hole in the ground lined with animal skin works. 10) Used for thousands of years before pottery.

Reference Card
Coal beds are better than flames (flames are uneven and hard to control; a bed of glowing coals provides steady, even heat for cooking). 2. Earth ovens are slow cookers (bury food with hot rocks and come back hours later; the earth oven is the original slow cooker). 3. Never use wet river rocks (rocks from streams can contain trapped moisture that turns to steam and causes the rock to explode violently). 4. Stone boiling works in anything (you can boil water in a bark basket, a skin bag, or a hole in the ground; hot rocks transfer heat to water instantly). 5. Wrap food in leaves (green leaves protect food from ash and add moisture; banana leaves, corn husks, and grape leaves all work). 6. Green wood does not burn quickly (use green (living) wood for grills, spits, and cooking racks; it chars slowly instead of catching fire). 7. Clay-baked food is self-basting (coating meat in clay and baking in coals seals in all moisture; the clay peels away with skin and feathers). 8. Fire management is cooking skill (controlling your fire, building proper coal beds, and managing heat is more important than any recipe).
