Abstract
Disclosed is a flexible package holding a foodstuff to be cooked therein. The package includes an interior space in which the foodstuff is located and a panel from which a fin projects. The fin includes at least one vent formed by a peelable interface having a first end in communication with the interior space and a second end in communication with the ambient atmosphere outside of the package. The peelable interface forms an openable passageway tapering from the first end to the second end and opens in response to steam produced within the package when the foodstuff is cooked, whereupon the steam can exit the package through the passageway.
