In addition to being inexpensive, cast aluminum is lightweight and provides good thermal conductivity, ensuring that the food heats evenly. This helps to prevent the scorching and burning of food. It also doesn't rust and is resistant to corrosion. It is thicker and harder than spun aluminum.
Aluminum can potentially be reactive to acidic foods, changing the taste. It is best to avoid cooking foods that are salty or acidic, such as tomatoes, fruits and vinegar-based sauces.
Some claim that cooking with aluminum cookware can potentially lead to Alzheimer's disease or other health problems. However, scientific research has yet to prove any of these claims. According to the FDA, a single aspirin will place more aluminum into your system than cooking or storing an entire day's meals on aluminum.
New Cast Aluminum Cookware
Newer cast aluminum pieces are covered with a nonstick plastic that food doesn't easily stick to. Most newer pieces are also ovenproof up with 400 degrees F as well as being dishwasher safe for your convenience. Because of the improved hard surfaces and technologically advanced plastic surfaces, these new cast aluminum pieces are virtually scratch-proof, even with metal utensils.
It is best to only use cast aluminum cookware if it is in good condition. Avoid using it for food storage, as during storage the food can absorb more than the normal amount of aluminum, making it possibly unsafe.
