Superior Choice – Inert, Non-Reactive Cookware
Earthenware and ceramic
are inert and they emit a far-infrared heat, the most effective and beneficial heat for cooking, which enables a full range of subtle flavors to emerge. Excellent for lengthy simmering and baking, these beautiful but breakable items require special handling.
Do not purchase ceramic-coated cookware. Just like other non-stick cookware, the synthetic ceramic surface layer degrades with normal use. Purchase only 100% ceramic cookware; it is nonreactive, contains no toxic metals or synthetic polymers and it withstands erosion and temperatures up to 1800 degrees Fahrenheit. Only diamonds and sapphire have harder surfaces than ceramic.
Spanish cazuelas and older Romertopf baking dishes are excellent earthenware choices and you may find casseroles and pie pans from your local potter. (Note: antique ceramic or earthenware pots may contain lead. Inexpensive lead-testing kits are available at hardware stores.)
Enamel
is a fused glass surface overlaying a light metal–or a heavier cast iron–pot. With proper care, quality enamel cookware lasts a lifetime. There are various brands available; do an on-line search for users comments to determine the line that best suits you. Note: inexpensive enamel cookware has only a thin layer of enamel and is not as durable as that with two or more layers.
Discard chipped enamel cookware. Once the underlying metal is exposed, it reacts with food and enamel fragments find their way into your food.
Glass
coffee pots and casserole dishes are inert and affordable. Favor glass containers for storing food. By the way, if you’ve got old glass bake ware, don’t replace it with newer glass! Pyrex and Anchor Hocking, our two major domestic producers of glass bake ware, are currently using a soda lime glass that can shatter under high heat. European glass wear is made from the more durable, and pricy, borosilicate glass, as was our domestic glassware prior to the 1980s.
Bamboo
steamers and paddles as well as wooden spoons, chopsticks and crockery are non-reactive and modestly priced.
Paper Goods
are, in some applications, effective. Line reactive aluminum muffin tins or cookie sheets with 100% un-bleached muffin cups or parchment paper. (Note: natural parchment paper is coated with non-reactive silicon, not the chemical quilon). And for food storage, as is practical, favor waxed or butcher paper over plastic wrap or bags.
Titanium
Note: While 100% Titanium is non-reactive, it’s too pricy for cookware. Titanium coated cookware is typically aluminum cookware with a fused synthetic polymer-titanium, nonstick coating. It is reactive and not recommended. SaladMaster’s line of surgical grade (316) stainless steel pots includes titanium;
A Good Choice – Moderately Reactive Cookware
Stainless steel
is the least reactive metal, and for many people, the most versatile and healthful cookware option. It makes an acceptable set of basic pots, pans and bake ware. Because it unevenly conducts heat, most stainless cookware is clad or encloses an aluminum core. The term “ply” refers to the number of layers; the higher the ply, the heavier the pot and the more resistant it is to warping. Most stainless steel is 18/10 meaning that it contains 18% chromium and 10% nickel. The 18/0 designates a nickel-free product.
Remove food from metal as soon as it is cooked to minimize it developing a metallic taste. Once stainless steel has been scratched by heavy scouring, it will leach chromium and copper (if it contains copper). Therefore don’t scour stainless cookware. When you’ve burned something onto the pot, cover it with baking soda, salt or a strong detergent and let it rest for a day or more if necessary. The soda will “lift” off the scorched food.
A stainless steel knife is less reactive than a carbon steel knife but it doesn’t hold its edge quite as well.
Carbon steel
is inexpensive, thin, lightweight and ideal for a wok or crepe pan because it rapidly conveys heat. With use, it will develop a non-stick like patina but prior to that do not use it with liquid or acidic ingredients and dry it thoroughly after every use to prevent rust. Since carbon steel is reactive, do not use a carbon steel knife for cutting acidic foods like citrus or tomatoes.
Cast iron
pots are good for quick breads, pancakes and for sautéing vegetables. Do not, however, use cast iron for soups, liquids or acid foods as these foods leach harsh-tasting iron from the pot. Although a soup cooked in cast iron becomes iron-enriched, this heavy metal is not bioavailable.
Silicone cookware.
If you use silicone cookware, purchase only 100% silicone that is FDA approved and safe up to 428 degrees Fahrenheit). This is critical as there are countless silicone formulas and some products, such as the popular bake sheets, are only silicone coated. But does an FDA approval mean that silicone cookware is non-reactive? Not according to a 2005 British study that determined while the overall the chemical migration from the silicon into foodstuffs was low, it does occur.
The advantages of silicone include heat resistance (below 428 degrees Fahrenheit), flexibility, the fact that it can go directly from the oven or microwave into the refrigerator or freezer and that it is generally easy to clean.
