Wood fires burn hotter than charcoal fires, so food often comes out burnt on the outside and uncooked in the middle. There are several ways to deal with this problem:

• Use a heavy cast-iron pan or dutch oven. The large metal mass helps mediate the heat. But obviously these pans are too heavy to use when backpacking.
• Use a double boiler. (here's a brilliant version to use when backpacking)
• Boil water and use it for stew, noodles, coffee, boiled fish, etc. The large amount of water serves a similar purpose to a double-boiler.
• Cook on top of a rock. [1] [2] [3] Use the right rock to minimize the chance of cracking or exploding.
• Use a pit oven.

There are several ways to support your pot:

• A pot hanger, which come in numerous configurations: [1] [2] [3]
• A Swedish candle. [1] [2] [3] [4] [5]
• Strategically placed rocks.
• A Dakota fire hole, though it takes more work.

Other tips:

• It's important to maintain the fire correctly. The wood goes from flame ⇒ coals ⇒ ash; you want to accumulate a good bed of coals. [1] [2] [3] [4] [5] [6] [7] [8] Use hardwood not softwood, because it burns longer and cooler.
• Your food should be just next to the flames, it shouldn't be directly over the flames
• The hanging pots are called "billycans".
  • The Zebra brand is very popular, however, billy cans originated from cheap DIY cans. (since they get all sooty, you may not want to spend a lot on them) [1] [2] [3]
  • Many tea kettles work as-is, since they normally come with handles.
