Boil-in-Bag

Boil-in-bag is a packaged-food method in which food is sealed in a plastic pouch and cooked or heated directly in boiling water. Solid, impermeable bags hold frozen prepared dishes that are simply submerged in hot water for a set time, while porous or perforated bags let boiling water penetrate the pouch, suiting dry goods such as grains. The most common boil-in-bag product is rice, though other cereals and grain-based foods use the same packaging, typically a temperature-resistant polypropylene bag, and the method became popular as a convenience-food option sold alongside canned and frozen alternatives.
