A few years back I started cooking on cast iron. It's now my preferred method of cooking, but in the beginning I was so frustrated that I nearly threw them in the cupboard for good!
What makes cast iron so great?
Cast iron is great for many reasons. The first people mention is that it'll last hundreds of years if you maintain it properly. That means the cookware you're using now can be passed down to your children, grandchildren, and even GREAT grandchildren. Saves them $30, and they can't complain that you never gave them anything.
Cast iron is also perfect for searing food. Copper and aluminum can't sear the way cast iron can. Since cast iron skillets are made out of one piece of iron, there is no issue with warming it in a 500°F oven in order to get a great sear on a steak. If you like cooking steak, cast iron is definitely the way to go. It can also be used over a campfire, or any other open flame. Just be sure to use a thick oven mitt or towel when you pick up the handle.
Cooking with cast iron is also a healthier alternative to cooking with aluminum, copper, or non-stick cookware. A properly seasoned skillet has no toxicity, where the only "leaching" being done is an essential mineral: iron.
But if you're used to cooking with aluminum or copper cookware, there are some adjustments you're going ot have to make in order to cook with cast iron.
Cooking Tip 1: Pre Season
When you first get your cast iron skillet, you want to make sure it's seasoned properly. Many bought today come pre-seasoned. "Seasoning" a cast iron skillet involves washing it with soap and water (the only time you use soap on cast iron), drying it completely, then covering it in vegetable oil and letting it cook inside an oven. I've read different temperatures and times, ranging from between 300°F to 400°F for as long as 1 to 3 hours (depending who you ask). Some instructions even suggest repeating the process up to three times! With seasoning, buy pre-seasoned, or use your best judgement. Clean it, coat in vegetable oil, then cook it in the oven.
Cooking Tip 2: The Setup
Once you've seasoned it and have been cooking with it for a while, it might look something like this:
It's okay if there are small amounts of food particles left over from past meals. Any bacteria will burn up once you cook with it again. I've been using this pan for a few years cooking eggs and chicken breasts nearly daily and have not had any stomach issues. Each time you cook, you want to gently scrape any food off of the surface with something wooden or plastic, never sharp metal (metal will scratch the surface of the cast iron which could scrape off the seasoning and/or cause rust).

A good time to apply some kind of oil to the skillet is before cooking. Some people use coconut oil, some vegetable oil, but I like to use bacon grease (more info on that below).
Cooking Tip 3: Reduce Temperature
This is where I became frustrated in the beginning. When I used to cook eggs in aluminum or copper skillets, I'd use high heat (8/10). Whenever I tried that with cast iron, the eggs would burn and get stuck to skillet causing a big mess. Everything I cooked on cast iron came out burnt. I thought "Is this what cast iron cooking is all about? Burnt food?" I convinced myself that cast iron was just a big, overrated gimmick, with too many "rules" that made cooking too much of a hassle. I gave up on cast iron for a while, until I learned that cast iron requires patience.
Where I used to use high heat (8/10) to cook with aluminum, I discovered eggs on my cast iron cook perfectly at med-high heat (6/10). It's important to pre-heat the cast iron for a few minutes before putting the food into the skillet. Cast iron takes longer to heat up, but once it does, the heat is more evenly distributed and consistant than other cookware. Keep the temperature lower than normal (compared to other cookware) and wait for the iron to "release" the cooked food before you try to flip it, and you'll fall in love with cast iron cooking.
Cooking Tip 4: Cleaning Up
The best time to clean cast iron is immediately after cooking while it is still hot. If you allow large food particles to cool on cast iron it becomes difficult to scrape away (but not impossible).
Once the particles have been scraped off, you can either wait for it to cool, or empty it into the trash. Be careful if you decide to empty it right away. Cast iron is heavy, so make sure you get a good grip on the handle. I like to grab the handle so that my palm is facing up before I pick it up. Then when I get to the trash can and turn the skillet upside down, my palm is also facing down. This gives me the most control while emptying the skillet. Whatever you do, you need a plan, because it's hot and you don't want your grip to slip and have the heavy cast iron skillet falling on your foot.
If you waited for the pan to cool down before scraping it off, then you might need to wash it. There are a couple of methods for washing. One method is to add water and then let the water boil in the skillet on the stove. This will help loosen all of the burnt pieces. Then, while the water is still boiling, you can take a wooden or plastic spatula to lightly scrape away all the junk that was stuck on the skillet. Once everything has been loosened, pour the water out into your sink (using a strainer to catch any debris is you don't have a disposal). Continue cleaning using a brush
Cooking Tip 5: Mini-Seasoning
If you removed the large food particles while the pan was still hot, then you can do a "mini-seasoning" by covering the skillet with oil and placing it back on the warm burner. The oil will slowly cook while the burner cools down.
These "mini-seasonings" are great for keeping your cast iron it top shape and ready to use for your next meal. It's a little extra work, but if done correctly, your cast iron cookware will last many lifetimes.
