What is a vented reservoir lid?
Vented reservoir lids have built in steam vents that can be opened and closed with one finger. The reservoir built into each lid collects liquid that may otherwise boil over the side of the cookware onto the stovetop and onto the bottom of the pan (the most difficult part to clean). Since the boiled-over liquid collects in the reservoir lid, your cleanup is as easy as lifting the lid and pouring the liquid back into the pan.
