Question: how to defrost chicken breast in 4 hours?
Answer: Place the meat in a leak-proof, zip-top bag to avoid the water getting in and making your meat soggy.
Submerge your bag in cold tap water, changing the water every 30 minutes.
Small bags (around 1 pound) may take up to an hour. A 3 to 4-pound bag may take 2 to 3 hours.
