Cook pots are made in various sizes, both in diameters and heights. This is important to take into consideration when choosing which stove to use with the cook pot, and especially if you are going for small solo cook pots, and using alcohol stoves with it. Also, pots are made of different types of metal. Most of the pots will be some form of aluminum or a titanium. There are different thicknesses and some of the pots may be some specialized type of alloy, such as hard anodized aluminum or GSI’s Halulite, among others. These different materials, and thicknesses, are all ultimately trying to get at more efficient heating and a lighter weight. However, some of the more specialized materials such as the Halulite, offer other benefits such as resistance to scratching and burning.
Some pots are even dual use in that they are used for both a cook pot as well as a bowl or a cup. These are typically 600 – 700 ml pots or less, but can even be up to .9 liter or 1 liter pots, however, some use a little as 400 ml cups as their stove / cup. Naturally this is saving weight by not worrying about carrying an extra bowl or cup. Things to think about when doing this is the fact that the pot is hot and will sometimes need to allow a minute or so to cool down before being able to sip from.
For use with two or more a bigger pot is needed, obciously. These typically are at least 1.5 liters or bigger, however some get away with using slightly smaller. This is just a personal issue. My wife and I typically carry our GSI Dualist cook pot and it is a 1.8 liter pot. It works well for us and I feel comfortable suggesting it to anyone.
Other options are tea kettles, and some even use Dutch Ovens. I know nothing of the Dutch Ovens so you will need to research this, and hardly anything about the tea kettles. What I do know about the tea kettles is that they are very effective at boiling water. Since these have a wide bottom, the flame from the stove is very effective at heating the water fast. I am looking into getting one of these for use with my White Box SOLO Stove. These are typically light-weight options.
Of course when it comes to cups and bowls and plates there are plenty of options. I myself do not use plates or bowls since I Freezer Bag Cook, and I am currently trying to move away form carrying cups, unless there is another person with me. However there are many options to choose from. There are plates that fold down flat, and others that squish up, while some bowls and cups simply store inside the cook pot nested together. The titanium cups are pretty popular with the light weight crowds, and there are actually single and double walled cups to choose from. Obviously, the double walled cups are slightly heavier, but they remove the issues of burning yourself on the them. And I am not 100% sure, but I don’t think that the double walled cups are supposed to be used directly on a stove, so these cannot pull double duty.
Also, there is utensils to take into consideration. One of the most common utensils found on the trail is the spork. And all sporks are not the same. Some have a fork on one end and a spoon on the other and even feature a serrated edge on the fork side which can be used as a knife. Others simply resemble a spoon with a few teeth on the end that creates the spork. Some have long handles, and some have short handles. Some people use the plastic ones typically found at Taco Bell while others want to buy the Titanium ones. There are lots to choose from, and again, this is a personal issue. I will say this though, match the length of the spoon to the container you will be eating out of. Using a short spork to eat out of a deep dish (freezer bag or cook pot) can be tedious.
