Four and a half liters of aluminum with a wire handle and a high lid. The reason to own one is in Trangia’s own sentence: “the whole stove can be packed into the billy.” Your 25 Large goes inside, and you get a group-sized pot for the same space.

On the stove you use it with the supports in the raised position, the way you would a frypan. Trangia also note it “can be used on other heat sources” — this is a pot that is happy on a fire.

It is the high lid now. Trangia state that “the flat lid is discontinued” — so if you have seen pictures of a flat-lidded Billy, that is the old one. This is the current high-lid version.

One caution Trangia publishes and we are going to repeat. On bare and anodized aluminum: “avoid cooking and storing acidic or salty foods in aluminum vessels for extended periods of time,” and maintain the surface to prevent scratches “that may increase the risk of metal release.” Tomato sauce overnight is the thing to avoid. If that is how you cook, the Duossal version of this pan has a stainless interior and sidesteps it entirely.

Care

Not dishwasher safe, and this is Trangia’s own position rather than ours: “the chemicals used in dishwasher detergent destroy the aluminum’s surface.” Hand wash with washing-up liquid and a brush or soft sponge. For stubborn residue Trangia permit steel wool or a scouring pad — on everything except non-stick.

Do not store food in the pots, and do not boil dry: Trangia warn that “without food or liquid, it can melt.” Keep plastic parts away from the flame.

Induction and oven use are not published by Trangia, for any of their cookware, so we are not going to claim either.
