Dry food in sun and wind

Slice food thin and let moving air take out the water that rot needs to live.

Rot is alive. Mould and the tiny living things that spoil food all need water to grow. Take the water out, and food stops being a home for them. It just sits there, safe, sometimes for months.

Drying is the oldest way to keep food, and the simplest. You need no fire, no salt, no pot — only sun, moving air, and patience. A basket of berries rots in three days. The same berries, dried, feed you in midwinter.

You need

• Food worth keeping — berries, fruit, roots, greens, or fish and meat. Mushrooms only if you are completely certain of them — deadly kinds like the death cap copy safe ones, and drying does not remove poison. Fresh and clean. Never dry food that already smells bad; drying keeps food as it is, it does not fix spoiled food.
• A sharp edge — a knife or a sharp stone flake, for slicing thin. Thin is the whole trick.
• Something to dry on — flat clean rocks, a rack of sticks lashed together, or cords strung between two trees. Air must reach the food from all sides, so a rack or a line beats a flat surface.
• A sunny, windy, open spot — wind matters more than heat. A breezy hillside dries food faster than a hot still hollow.
• A dry container for after — a basket, pot, or bag kept off the ground, for storing the finished food.

Steps

1. Pick or catch your food in the morning of a dry, sunny day. Check the sky — you want two clear days in a row.
2. Clean it. Wash off dirt. Gut and clean fish and meat completely — guts spoil first and fastest.
3. Slice everything thin — as thick as your little finger at most, and thinner is better.
   • Fruit: cut into flat slices or split berries open.
   • Roots: thin round slices.
   • Meat and fish: cut along the grain into long strips no thicker than a finger. Cut away all fat you can see — fat does not dry, it goes rancid (spoils into a bitter, off-smelling grease).
4. Lay the slices out with a gap between each piece, or hang strips over a cord. Nothing should touch anything else.
5. Keep flies off. Hang the food high in the breeze, drape loose thin cloth over it if you have any, or set a child to wave a leafy branch. Flies lay eggs on drying meat, and those eggs become maggots.
6. Turn the pieces every few hours so every side meets the air.
7. Bring everything under cover before evening. Night dew puts the water right back in. Set it out again next morning.
8. Test on the second day. Fruit is done when it is leathery and bends without wetness inside. Meat and fish are done when a strip cracks when you bend it sharply — bends softly means not done, keep drying.
9. Store the dried food in a container in a dry, cool, shaded place, off the ground. Check it every few days for the first week. Any dampness — dry it again.

Watch out

• Too thick is the number one failure. A thick piece dries on the outside and rots on the inside. If in doubt, cut it thinner.
• Rain and dew undo your work. One wet night can spoil two days of drying. Always bring food in before dusk and before any rain.
• Fat spoils even when dry. Trim it off meat. Oily fish keeps poorly by sun-drying alone — smoke it instead once you can.
• Flies and maggots. If you find maggots (small white wriggling grubs) in the food, that piece is lost. Throw it far from camp.
• Mould in storage. White, green, or black fuzz means the food was not dry enough. Throw mouldy pieces away — do not just brush the fuzz off, its roots go deep.
• Drying does not clean bad food. If food smells sour, rotten, or wrong at any stage, do not eat it and do not keep drying it. When in doubt, throw it out.

How it works

Every living thing needs water, including the invisible ones that rot food. Moving air carries water away from the food's surface, and thin slices mean no piece of the inside is far from the surface. Below a certain dryness, mould and rot simply cannot grow, so the food waits, unchanged, until you soak it or chew it.
