The humble roast potato beat turkey, stuffing and Christmas pudding as the most popular food on December 25.
Carrots took the second spot ahead of turkey, gravy, stuffing, ‘pigs in blankets’, parsnips, sprouts, Christmas pud and Yorkshire pudding.
The survey of 2,000 Brits by Asda highlighted December 5th as the day when folk really get into the seasonal swing. That's the day people put on the Christmas jumper, put the tree up and watch their first Christmas movie.
The average Brit will buy their first present on November 20th and eat their first mince pie on 29th November.
Asda said: "Christmas is one of those occasions that doesn’t need messing with too much.
“We’ve done our best this year to make traditional favourites that little bit more special and have won numerous awards for things like our new recipe mince pies, cranberry sauce and festive turkey – all key components for the perfect Christmas.”
The survey also pinpointed the day and time most people first start to feel a festive glow – 1.38pm on December 1.
