What foods actually work for cold-soaking?

Instant mashed potatoes, couscous, ramen, instant refried beans, and instant oats all rehydrate in 20-30 minutes cold. Avoid most freeze-dried backpacker meals — they're built around boiling water and stay crunchy or chalky cold.

How long does cold-soaking actually take?

Plan on 20-30 minutes for most quick-cook starches, longer for anything denser. Rae starts her dinner soak about 30 minutes before camp so it's ready when she stops walking.

Is a peanut butter jar fine as a cold-soak container?

It works, but a screw-top Talenti gelato jar is the thru-hiker standard — wider mouth, lighter, and the lid actually seals if it tips inside your pack. Replace it every few hundred miles before the threads give up.

Will I get sick eating cold-rehydrated food?

Generally no, as long as you start with shelf-stable dry ingredients and clean water. Don't cold-soak raw meat, eggs, or anything that needs heat to be safe — and eat the meal within an hour or two of mixing rather than letting it sit overnight.

How much weight do you actually save going stoveless?

Roughly 350-400g once you drop the stove, fuel canister, pot, and lighter — Rae measured 380g on her setup. On a long thru-hike that's meaningful; on a weekend trip it mostly just saves you fiddling with a canister.

Can I cold-soak in winter or shoulder season?

We'd skip it. Below about 50°F at night, a hot meal is doing real work for your core temperature and morale, and food rehydrates noticeably slower in the cold anyway.

What's a good first cold-soak meal to try?

Instant mashed potatoes with a peanut butter packet and a few dashes of Sriracha. It's idiot-proof, rehydrates in about 20 minutes, and tastes legitimately good even if it looks like wallpaper paste.

Cold-Soaking on Trail: When It's Worth It and When It's Just Sad

By Rae Donovan · April 26, 2026 · 2 min read

Rae cold-soaks half her trips and cooks the other half. After enough nights both ways, the answer to “should I ditch my stove?” is genuinely “it depends.”

Where cold-soaking wins

Trips under 5 nights with mild weather (50°F+ at night). Saved 380g of stove + canister + cup; food still tastes fine because everything is heat-tolerant.
Long thru-hikes where you're moving 25+ miles a day. The 15 minutes saved morning + evening adds up.
Fire-restricted zones where stoves with adjustable flames are also banned.

Where it loses

Cold weather. A hot meal at 35°F is the difference between sleeping and shivering. Don't cold-soak in shoulder season.
Group trips. The morale hit of watching your buddies eat hot mac and cheese while you have lukewarm couscous is real.
Anything dehydrated that takes >30 minutes to rehydrate cold. Most freeze-dried meals fail this test.

The peanut-butter-on-everything cheat code

Cold-soaked instant mashed potato + peanut butter + Sriracha is the unofficial PCT thru-hike dinner and it's actually good. Looks horrible on Instagram. Don't care.

Bottom line

If you're hiking solo in summer for under a week, try it once. If you're carrying for a partner who likes hot dinners, just bring the Jetboil. The 380g is worth the relationship.
