A piece of cast-iron cookware is a staple in any chef’s kitchen. It can be used for stovetop cooking, oven roasting, and even deep-frying. Not to mention the fantastic results campers and other camp cooking enthusiasts achieve when using their cast-iron cookware over flames or using briquettes.
However, there are some foods that should not be cooked in a cast iron skillet, pot, or iron pans.
You should not cook acidic sauces and foods such as tomatoes, lemons, and other citrus foods, delicate proteins like white flakey fish, and eggs. Also, sticky foods, such as desserts with sugary sauces before carrying out a thorough seasoning of your cast-iron Dutch oven, skillet, or pan.
What is Cast-Iron Cookware?
They are sturdy and heavy cooking pots, ovens, and skillets (just to name a few) manufactured from iron that is then seasoned to create a non stick surface. The seasoned surface not only stops your food from sticking to the surface of the iron but protects your cast iron from rusting or worse – corroding.
You will also find cast-iron cookware in the form of cast-iron coated in enamel that is suitable for use in a kitchen not on a campfire.
Sometimes you will also find similar cookware that is made from ceramic, aluminum, stainless steel, and various other metals. They can be coated or uncoated.
Cast-iron skillets, pots, and pans are made all in one piece when manufactured. They are made from molten iron that is then poured into casts.
Dutch ovens are made the same way all in one piece. The pot has handles molded in one piece with the oven used for moving them safely during the cooking process. They have fitted lids that are heavy and tight to keep the steam inside the pot. The lid loop is also in one piece molded along with the lid.
Unlike a regular nonstick pan, a nonstick skillet made from iron can withstand higher temperatures and one of the best things about a hot pan like this is its heat retention.
Cast iron pieces of cookware are known to have a long-lasting and extended lifespan. The long life span can be attributed to the great care and maintenance of a good quality piece of cast iron.
