What for lids are used on saucepans?

Lids are used on saucepans to:

* Prevent heat loss: A lid helps to keep the heat inside the saucepan, which reduces the amount of time it takes to cook food.

* Prevent evaporation: A lid helps to prevent the water in the saucepan from evaporating, which means that you don't have to add as much water during cooking.

* Keep food from splattering: A lid helps to prevent food from splattering out of the saucepan, which can keep your stovetop clean.

* Direct steam: Some lids have a small hole in the center, which allows steam to escape. This can help to prevent the food from boiling over.

* Seal in flavor: A lid helps to seal in the flavor of the food, which can make it more delicious.
