There’s a good chance that you have an aluminum pot or pan sitting in your cupboard. Aluminum cookware is inexpensive, efficient, and a great heat conductor. The drawback is that some acidic foods, such as tomato sauce, leach the aluminum into food. Most aluminum is excreted through the kidneys, but that doesn’t change the fact that it has been deemed a top-priority toxin by the United States Agency for Toxic Substances and Disease Registry. One alternative is to purchase an aluminum pan treated with anodization, which prevents the aluminum from leaching, or use one of these specially designed braising pots.
