'I cook my Christmas dinner in five air fryers'

Ms Jarvis shared her recipe for an oven-free Christmas dinner. "Try a turkey breast roll - you can either ask the butcher to do it or buy one in the supermarket," she said.

She said an average-sized turkey breast roll that would feed six would take 55 minutes at 180C.

"The bigger air fryers will take a bigger bird."

But what about the much-loved roasties? "The brilliant thing is that you can add the potatoes towards the end and give them 35 minutes," she said.

"Just turn it up to 190C; you'll get wonderful crispy potatoes with your turkey roll."

And for side dishes and snacks? "You can do pigs in blankets; they will take about 10 minutes at 190C," she said.

"Sausage rolls are a cinch - 15 minutes at 200C will produce delicious, crispy sausage rolls.

"They're better than perfect."

Ms Jarvis said she has experimented with cooking other meats in her air fryers.

"Gammon is fantastic. I cooked the whole thing in the air fryer, quite a big piece of gammon for 10 people, and it was absolutely delicious," she said.

"At the end, I glaze it with maple syrup, marmalade and, in my recipe, a bit of whiskey."

Ms Jarvis said she wrapped the meat in foil and placed onions and carrots below.

She also recommended an alternative festive snack, which included grating half a block of parmesan, adding a quarter of teaspoon of chopped chillies, a few pumpkin seeds and herbs.

"You literally take the base plate out of the air fryer, heat it to 200C, very lightly oil the base, then put soup spoons of your cheese in blobs around the base," she said.

"They take four minutes at 190C, and they go lacey and crispy, and they are delicious with a glass of bubbly."
