Cold soaking is preparing backpacking meals by rehydrating food in cold water in a sealed container over time, instead of cooking with heat. It lets ultralight hikers leave the stove, fuel, and pot at home, saving weight and time, at the cost of meal variety, palatability, and warmth.
Why and when
A weight-cutting tactic of ultralight backpacking — ditch the camp stove entirely. Many keep a canister stove for cold-weather morale.
Frequently asked questions
What is cold soaking?
Cold soaking is rehydrating food without cooking — you put dried ingredients (like couscous, instant beans, oats, or ramen) in a sealable jar with cold water and let them absorb it over 30 minutes to a few hours until edible. It eliminates the need for a stove.
Why do backpackers cold soak?
Mainly to save weight and hassle: no stove, fuel, pot, or lighter to carry, no cooking time or fire risk, and less to clean. Ultralight and thru-hikers adopt it to shave pack weight and simplify camp routines, especially where fire bans are common.
What are the downsides of cold soaking?
No hot meals or drinks (a real morale and warmth hit in cold weather), limited food choices to things that rehydrate cold, longer soak times that need planning, and textures some find unappealing. Many hikers cold soak only in warm seasons or carry a stove as backup.
