Mastering Cast Iron Cookery
Printed in full here from the book.
Oven seasoning
That layer makes the pan non-stick and keeps rust out.
- Wash and dry Wash the bare pan in warm, soapy water with a stiff brush, then dry it completely on a low burner.
- Thin coat of oil Wipe a very thin coat of cooking oil over every surface, inside and out, then wipe it nearly dry.
- Pan upside down Line the lower oven rack with foil and place the pan upside down on the center rack.
- Bake 1 hour Bake at 450 to 500°F for 1 hour.
You need: Cool in the oven (Turn the oven off and leave the pan inside until it is cool.)
Check it. Pass: the surface is dark, smooth, dry and slightly glossy with no sticky or pooled spots. Fail: any tacky patch, any orange rust or any oil that ran into drips.
Field check
- I wash the bare pan in warm, soapy water with a stiff brush.
- I wipe a very thin coat of cooking oil over every surface.
- I place the pan upside down on the center rack.
- I bake at 450 to 500°F for 1 hour.
- I leave the pan inside until it is cool.
Safety. Keep a rag or mitt handy when you take a pan out of the oven. Cast iron stays hot long after the fire is out.
Camp clean and re-oil
Clean the pan soon after cooking, while it is still warm.
- Scrape out loose food Scrape out loose food while the pan is still warm.
- Scrub with hot water Scrub with hot water and a stiff brush, scraper or chainmail scrubber. Add coarse salt for stuck spots.
- Simmer and scrape For burnt-on food, simmer a little water in the pan and scrape with a wooden spoon.
- Dry the pan Dry the pan on a low burner or beside a gentle fire until no moisture is left.
- Rub on oil While it is still slightly warm, rub on a thin coat of oil and wipe off the extra.
You need: Store it dry (Store it dry. Put a paper towel between stacked pieces.)
Check it. Pass: no moisture when you wipe it with a white cloth, no rust spots and a light shine. Fail: any damp spot, any orange mark or any sticky surface.

Rust restoration
A rusty pan is not ruined.
- Scrub off rust Scrub off all rust with steel wool until bare gray iron shows.
- Wash and rinse Wash the pan with soap and water, then rinse.
- Dry it completely Dry it completely on a low burner.
- Wipe on oil Wipe on a very thin coat of cooking oil, inside and out.
You need: Bake and cool (Bake it upside down at 450 to 500°F for 1 hour, then let it cool in the oven.)
Check it. Pass: no orange anywhere and a dark, even coat after the bake. Fail: any rust left or patches that stay dull after the bake.

Cast iron in camp
Season, cook with, clean and restore cast iron so it stays rust-free, non-stick and ready for the fire.
- Camp workhorse Cast iron has fed cooks for centuries. It was the main pot of pioneers and early woodsmen, and it is still the workhorse of the camp kitchen.
- It holds heat It holds heat. Once hot, it stays hot, which is ideal for searing, frying and slow cooking over the uneven heat of a fire. It heats evenly, with few hot spots.
- Tough and seasoned It is very tough and handles heat and hard use that would warp thinner pans. A well-seasoned pan has a smooth, non-stick surface with no synthetic coating. It works on flames, coals, a stove and an oven.
- Care and portages Research suggests some iron may pass into your food, though more research is needed. With care, one piece can outlast you and become a family heirloom. On a canoe trip the weight counts, so decide with your portages in mind.
What you need. A cast iron skillet or Dutch oven A stiff brush, plastic scraper or chainmail scrubber A cooking oil Rags or paper towels Coal and Dutch oven heat control (see the fire and stove chapter)
Field check
- I decide with my portages in mind.
- I keep my cast iron pan well seasoned.
- I cook on flames, coals, a stove or an oven.
- I have a stiff brush, rags and cooking oil.
Safety. Cast iron stays hot long after the fire is out. Use a lid lifter and leather gloves to handle hot lids and pans.
What seasoning is
Seasoning gets better with use.
- Baked in oil Seasoning is not just oil on the pan. It is oil that has been baked into a hard, polymerized layer on the iron. That layer makes the pan non-stick and keeps rust out.
- Wash and dry To season a new, bare pan, wash it in warm, soapy water with a stiff brush. This is the one time soap is a must. Dry it right away and completely. A few minutes on a low burner gets all the water out.
- Rub on thin oil Rub on a very thin, even coat of oil on every surface, inside and out. Use a cooking oil or a cast iron seasoning oil. Wipe it until it looks nearly dry, so no oil can run or pool.
- Bake it upside down Place the pan upside down on the center rack, with foil on the rack below to catch drips. Bake at 450 to 500°F for 1 hour. Turn the oven off and let the pan cool inside.
Practice it. Learn it on the table: season a thrift-store skillet in the kitchen oven. Then in the dark: clean and re-oil the pan on a camp stove by headlamp. Then wet: restore a lightly rusted pan after it sat out in the rain.

Cleaning and care
Clean the pan soon after cooking, while it is still warm.
- Brush and scraper Food comes off easily then. Use hot water and a stiff brush, a plastic scraper or a chainmail scrubber. One maker does not recommend steel wool or a metal scrubber for daily cleanup, but says it is fine for removing rust.
- Soap and dishwasher Old advice said never use soap. Today’s mild dish soap will not harm a well-seasoned pan, and one maker says soap is fine. Plain hot water is often enough. If you use soap, use a little and oil the pan afterward. Never put cast iron in a dishwasher.
- Stuck food For stuck food, add a little water, bring it to a simmer and scrape with a wooden spoon. You can also scrub with coarse salt.

- I clean the pan soon after cooking, while it is warm.
- I never put cast iron in a dishwasher.
- I dry it completely until it is bone dry.
- I wipe on a thin coat of cooking oil.
- With no oven, I scrub off the rust, wash, dry on a low burner and oil the pan.
Safety. Cast iron stays hot long after the fire is out. Use a lid lifter and leather gloves to handle hot lids and pans.
- Dry it completely Dry it completely. This is the most important step. Rust is the enemy. Set the pan on a low burner or beside a gentle fire until it is bone dry.
- Oil and store While it is still slightly warm, wipe on a thin coat of cooking oil and wipe off the extra. Store it in a dry place. When pans are stacked, put a paper towel between them. Dry it, oil it, store it dry.
- Rusty pan A rusty pan is not ruined. Scrub the rust off with steel wool, then wash, dry and season again. With no oven, scrub off the rust, wash, dry on a low burner and oil the pan until you can season it.

Heat control
Preheat slowly and fully before the food goes in.
- Slow preheat Cast iron takes time to heat and then holds its heat very well.
- Direct flame A direct flame is the hottest. Use it for a quick sear or a fast boil, and watch that you do not burn the food.
- Coals and stove Glowing coals are the best source for most cast iron cooking: simmering, baking and frying with steady, even heat. A camp stove is the easiest to adjust, and it suits both delicate cooking and a hard sear.
You need: Frying over coals (For frying, put a hot bed of coals right under the skillet. There is no shortcut for experience.)
Read your coals. Watch the food and learn to read your coals.

What to cook
In all cases, check meat with a thermometer.
- Skillet A skillet fries, sears and bakes. Think scrambles, bacon, fried potatoes and pancakes for breakfast, and steak, fried chicken, stir-fry, cornbread and biscuits for dinner. Heat the skillet before the food goes in for a better sear.
- Dutch oven A Dutch oven stews, roasts and bakes. Stews and chili simmer for hours over coals. Whole chicken, pot roast and pork shoulder come out tender.
- Camp oven baking Cobblers, cakes and brownies turn it into a camp oven. Put more coals on top for baking and more below for stewing.
- Griddle A griddle gives flat, even heat for pancakes, eggs, bacon, hash browns, quesadillas, grilled sandwiches and smash burgers. Keep it well seasoned.
Keep cooking. The more you cook with fat, the better it gets.
