When you finally decide to get a new cookware set, chances are you had your old pots. Of course, you are not cooking on an open fire with firewood, the caveman era is long gone. You need to check what you need to add and replace. A cookware set with just a few pots and pans will do. However, if you plan to get rid of the old cooking pots and replace them with new ones, then a cookware set with more pots and pans is the best choice.
Secondly, you have the choice between a flat bottom and a round bottomed designed. The first is the most common and works well for smooth top range of cooktops. The latter however, is the ideal choice when working with a vented ring on the cooker.
You also need to consider your individual style of cooking. If you like to fry meat often then stainless steel allows the meat to brown evenly. If say you like making tomato sauce then copper cookware sets are to be avoided as they will impact on the taste.
The type of metal construction will determine how the cookware set performs. Some metals are better heat conductors than others. Copper for example, reacts to heat extremely fast. This also means that when you want to take down the heat, it will also respond quickly allowing you to prepare food easily and conveniently.
You want to go for a cookware set that is durable. Cast iron will last longer than copper which dents very easily.
Price is an important factor and one that is always there in the mind of the buyer. As with most products, price is often a signifier of quality. As a rule of thumb, go for the most expensive cookware set you can afford.
