$55 - $145 stainless steel cookware lids come in a range of designs that control temperatures and the way moisture is returned to food during cooking. Domes of different specifications help condensed steam to baste the dish automatically. Flat lids allow tilting so that evaporation rises outside the pot, allowing sauces to thicken naturally without the need for agents. The fit of the lid affects how well temperature is controlled inside the pot. It is crucial that the ingredients inside tall pots are kept at the same temperature as those in the bottom. Those designed specifically for steaming guide condensed water down the sides of the pot to prevent sogginess and to return water to the boiler. $55 - $145 stainless steel cookware lids are designed to suit the diameter of cookware's rims and can be paired with pots that share the same brand to ensure a snug fit.
