Chicken may be thawed in cold water in its airtight packaging or in a leak-proof bag. Submerge the bird or cut-up parts in cold water, changing the water every 30 minutes to be sure it stays cold. A whole (3- to 4-pound) broiler-fryer or package of parts should thaw in 2 to 3 hours. A 1-pound package of boneless breasts will thaw in an hour or less. Cook immediately after thawing.
