Optimizing canister stoves in cold weather

Canister stoves typically see a decline in performance in cold weather.  During burning the fuel inside the canister evaporates, causing the canister to cool.  Moisture in the air will condense or freeze on the outside of the canister further chilling the gas inside the canister.  The temperature inside the canister can drop to a point where the liquid fuel inside the canister won’t evaporate appropriately.  Setting a canister in a pool of water, it can be as little as an inch, it keeps the frost from condensing on the canister and chilling the gas inside. Other ways to increase the effeciency of the canister is to start off with warm canisters.  Keep them deep in your pack or in your sleeping bag so they start off warm.  Use a windscreen and keep a lid on whatever you are cooking.
