Every household cooks their roast dinner differently on Christmas Day - some chefs cram their turkeys with sage and onion stuffing while others wrap theirs in bacon. But Dame Mary Berry opts for a far more unconventional technique to ensure her turkey is juicy and perfectly cooked on December 25.
The former Great British Bake Off presenter spilled her cooking secret on the Dish podcast to co-hosts Nick Grimshaw and chef Angela Hartnett - revealing that she'll be wrapping her Christmas turkey in an old sleeping bag while she enjoys a festive tipple with her family on the big day.
The 87-year-old told listeners: "I roast the turkey at home, and I've learned not to overcook it. So many times, even I have overcooked it.
"This time I'm cooking it without foil, I shall cover it with foil once it's done, then I shall put some tea towels over the top.
"I've got an old sleeping bag that's got no zip and I put that over the top in the corner of the kitchen and then I shall take that in the back of the car to Annabel's (Mary's daughter).
"Once you take it out of the oven, it goes on cooking. And so you want to insulate that.
"I shall pop it in the back of the car inside its sleeping bag and we'll be having drinks and lots of jollity until we need to carve it."
So, if you've ever wondered how Mary Berry will be spending her Christmas Day, now you know.
The rather unusual procedure sent Lorraine Kelly into stitches today on her morning show, and Alison Hammond called the idea "genius" later on This Morning.
"Obviously I'm going to wash the sleeping bag first, but I'm going to try this," she chuckled.
"Everything Mary's said, we curtesy, she's right, I worship at her alter we all do," Vanessa Feltz added
Mary will be returning to TV screens over the festive period for her new programme, Mary Berry's Ultimate Christmas that will air on Monday 19 December on the BBC.
