what types of pots good for cooking
Cookware is made in a variety of materials; each has different characteristics, and it is important to understand them before you buy. Many cooks purchase individual pots and pans in different materials to suit specific uses, rather than a full set in one material. Aluminum (moderate cost; recommended for all-purpose cooking): This versatile material is the most commonly used for cookware. Cast aluminum has a thick base and thinner sidewalls.
Copper (high cost; recommended for browning and sauces): This is a superior cookware material. Copper reacts with certain foods, so the cookware must be lined with tin or stainless steel. Never cook or serve in unlined copper pots or pans. Advantages: Exceptionally good looking; excellent heat conductor; durable. Disadvantages: Needs frequent polishing; any cracks or scrapes in the lining mean the cookware must be relined.
