One of the best cookers for heating up your food or sterilising water on is an alcohol stove. The alcohol stove is good as the fuel is more compact than a gas cooker's gas canister. the alcohol stove is also easy to maintain meaning that you wont get any malfunctions like you can get in a gas stove. This is why the alcohol stove is the best way to get hot food down your gullet in a remote location reliably.(nothing is worse than cold food when it is pelting down with rain and you've been hiking all day.
the BCB is a good alcohol stove that is simple to use the only problem may be the weight V a gas cooker it weighs around 1.5kg
