I love the JetBoil flash. If you are not familiar with it, this little stove boils a couple of cups of water in a few minutes. Great for coffee, tea, and instant meals that need boiling water. Just remember to keep the fuel canister warm.
Leave the fuel outside on a cold night and you will not have hot coffee in the morning. To avoid this, put the cannister in your sleeping bag and your body heat will keep it warm. You can also, put it under you arm pit a minutes to warm it up. Works everytime!
