The Adventure Menu Self-Heating Capsule is a 60 g capsule that heats two 400 g Adventure Menu meals through an exothermic reaction triggered by adding water, with no stove, fuel canister or flame involved. That makes it useful where an open flame or gas stove is restricted — fire bans, huts with cooking restrictions, or indoor use — and as a stove-free backup.
At 60 g for two meals it is lighter to carry than a stove plus fuel for a short trip, but it only works with the matched Adventure Menu pouches rather than any meal, and a single capsule cannot be reused once triggered. It suits situations calling for hot food without cooking gear rather than being a general-purpose camp stove replacement.
