On Thursday night I took some frozen chicken breasts out of the freezer and popped them in the fridge to defrost intending to use them the following day. They had been bought fresh but I hadn't used it all so froze the remains about a week previously while still in date. On Saturday I took them out of the fridge to make a chicken curry which I quickly cooled and refrigerated intending to eat tonight. However, when I was cutting the raw breasts up I noticed a couple of small areas had a slightly greenish metallic tinge. I'm now wondering if I should be serving that curry tonight. We gave a hectic few days coming up and can't afford to be ill?!!!
