Even the best-seasoned cast iron skillet won't perform well if it's not properly preheated. The key is to heat the empty pan sufficiently first and then add oil before proceeding with the recipe.
When using carbon-steel and cast-iron pans, some people like to heat the dry pan first, then add the oil. This is because high heat causes the oil to oxidize and polymerize, allowing it to bond to the metal, filling in any small pits and divots—a process that seasons the pan, essentially giving it a nonstick surface.
For individuals with diagnosed iron deficiency or anemia, cast iron cooking alone is not going to provide enough iron, and additional dietary modifications or iron supplements may be necessary." It's also worth noting what type of iron you'll absorb from employing this material in the kitchen.
5 Cast Iron Cleaning Mistakes Almost Everyone Makes—and How to Fix Them

The myth that you shouldn't wash your cast iron skillet with soap is just that — a myth. It's driven by two theories. The first is that since oil is used to season the cast iron skillet and create a nonstick surface, soap would effectively wash away the cure that you worked so hard to build.
Symptoms of iron-deficiency anemia may include:
Health Benefits: If you're wondering whether cast iron or pure iron is better for your health, the good news is that both are excellent. They both leach small amounts of natural iron into your food, helping to boost your daily intake. Maintenance: Both need seasoning with oil to stay rust-free and smooth.
Here are three effective ways to boost your iron levels.
Great options include red meat, liver, seafood, beans, lentils, spinach and fortified cereals. Consuming vitamin C with iron-rich foods can enhance absorption, so try pairing them with citrus fruits or tomatoes.
Add cooking oil after preheating.
If your cooking oil is heating for too long before you start cooking it could reach it's smoke point and start to polymerize, which could turn sticky and smelly. Plus, a hot pan helps the oil spread thinly and evenly over the cooking surface.
Avoid ruining the seasoning or worse — destroying your favorite skillet — by following these rules
If you have a thermometer, just check the oil to find out the temperature. The ideal oil temperature for most frying is between 350 and 365 F. If your thermometer says that, you're good to go.

Cooking with cast iron can increase iron intake, potentially benefiting iron-deficiency anemia. However, frying in cast iron can lead to the formation of trans fats. Teflon (PTFE) coating in nonstick cookware has raised health concerns due to the release of toxic gases and chemicals at normal cooking temperatures.
Daily cooks may only need to season every few months; occasional users should season every 2–4 weeks. Signs your pan needs seasoning: food sticks, surface looks dull, rust appears, water doesn't bead. After each use, clean, dry thoroughly, apply thin high-smoke-point oil, heat until it smokes, then wipe.

Any food-safe cooking oil or shortening will work, but our Test Kitchen experts prefer vegetable oil or canola oil. WHAT'S THIS DARK RESIDUE I SEE WHEN I CLEAN MY CAST IRON? Occasionally, you may notice some dark residue on your paper towel or cloth while cleaning it.
Vinegar reacts with baking soda to yield carbon dioxide gas and water. The carbon dioxide gas creates the bubbling effect of this reaction. If a small amount of dish soap is added, the bubbles will become trapped to form a thick foam. This happens because dish soap reduces the surface tension of water.
Detergents aren't made with lye, so can't be soap. Either way you still shouldn't use soap with cast iron, but can use detergents, though there is no reason to do so. You can easily clean well maintained cast iron without it.
