Check the water frequently to be sure it stays cold. Change the water every 30 minutes. After thawing, cook immediately.

It is safe to cook foods from the frozen state. The cooking will take approximately 50% longer than the recommended time for fully thawed or fresh meat and poultry.

It’s also important to use food within 24 hours after it’s been fully defrosted
