I bought an Oakham Chicken at the Southgate branch of M&S on 9/7/20. I prefer the corn fed chickens but the only one left on the shelf was best before 11/7/20 and although I was planning to cook it on the 11th, I prefer to have a day or two in hand in case anything comes up and I don't get a chance to cook it. I have bought Oakham chickens before and I know that they are much fattier than the corn fed and the meat is tender to the point of being flabby. I have an ordinary mid-range, Bosch fan oven. I put the Oakham chicken in to roast and within about 45 minutes the kitchen and whole house were filled with a fine film of smoke. There was an obvious smell of burning fat. I'd put the chicken in a deep roasting pan and it was just as well as fat poured out of the thing. I've never seen anything like it. This was a medium sized chicken bought to provide two meals for two people but the fat came halfway up the pan and once I'd got the chicken out of the pan, the fatty mess it left behind wasn't OK for making gravy and I poured it down the sink. This morning the inside of the oven is covered with a film of fat and the house still has a lingering unpleasant smell. This is my fault to some extent because I didn't look at the price. What can you expect for £3.50? On the other hand it's clear that the quality of these chickens is falling fast. What can they be fed on to produce such fatty meat and how 'healthy' can meat like this be? If this is the standard of chicken used in other M&S dishes then I'm totally out of love with M&S foods.
