More than a quarter of Brits keep their guilty pleasure snack habits a secret.

Dame Prue Leith is to serve up some unusual food combinations in the wake of a new study

A new study has found four in five of us like to experiment with unusual flavours, but when it comes to unconventional food combinations, 27 per cent of those wouldn't dream of tucking in in public, and 15% wouldn't even do so in front of their partners.

Among the unusual combinations the LNER study discovered were crisps and chocolate (32 per cent), chips and milkshakes (20 per cent) and cheese and bananas (19 per cent).

Other stomach-turning suggestions included tuna and marmite, gherkins dipped in peanut butter, and mashed bananas with HP sauce.

The survey came as LNER are teaming up with Dame Prue Leith to serve up some unusual food combinations for the public to try at Newcastle station on 4 October.

The 'Great British Bake Off' judge said: “Train food has come a long way since my campaigning days 40 years ago as part of my position on the board of British Rail.

"It’s wonderful to see rail companies really pushing themselves to provide fresh, creative and local on-board menus... and I can’t wait to taste these unexpected creations made by LNER’s suppliers!”

The event is being launched in celebration of LNER’s onboard menus, which offer a rich tapestry of food sourced from local suppliers all across the country. Find out more about LNER’s latest menu at https://www.lner.co.uk/our-trains/catering
