In some embodiments, a cooking utensil comprises a pot with a lid that divides a cooking chamber in the pot from a condensing chamber above the lid. To prevent boil-over, one or more openings in the lid and/or openings radially between the lid and the pot convey bidirectional flow between the cooking and condensing chambers. Boiling liquid/vapor foam from the cooking chamber flows upward through the opening to the condensing chamber. Upon subsequently flowing across an upper surface of the lid, the liquid/foam condenses and then returns through the opening to the cooking chamber. In some examples, the cookware includes both a mechanical seal and a liquid seal between the lid and the pot. In some embodiments, a single opening in the lid maximizes the lid's condensing surface while still allowing sufficient flow between the cooking and condensing chambers. Such a single opening also makes the cookware easy to clean.
