The grilled cheese and chilli jam crisps are now on sale in the likes of Asda, Tesco, Morrisons, B&M and Home Bargains

A mum who entered a Walkers competition 'on a whim' now stands to pocket up to £500,000 if her 'unique' flavour proves popular.

Becky Dibble pitched a new idea to the crisps giant, opting for the 'perfect combination' of salty and sweet.

Her grilled cheese and chilli jam flavour was one of two picked for a limited-edition run, and major retailers including Asda, Morrisons and Tesco were now stocking packets.

The café worker from Shropshire, was scrolling through TikTok when she came across the Do Us a Flavour competition.

She told BirminghamLive she thought she'd 'give it a shot' as food was her 'big passion', having worked in hospitality for almost 10 years.

The 26-year-old said: "To win, Walkers wanted to see people’s flavour creations by uploading a video and using the relevant hashtags.

"I saw someone’s entry back in February when scrolling my For You page, and thought I’d give it a shot, not expecting much to come of it.

"I spent hours designing packets and flavours to try and capture Walkers' eye, turns out it did.

"I’m a sucker for salty and sweet as well so I feel like this is the perfect combination, and it’s what makes them so moreish too.

"I was honestly in shock when I got told I’d made it to the top two.

"It was such a surreal experience knowing what was to come and that I was actually in with a chance at winning up to £500,000 – all because I entered the competition on a whim one evening."

Becky will be going head-to-head with Lydia Houghton, 54, from Malmesbury in Wiltshire, who pitched a salt and pepper chicken flavour, inspired by her go-to Chinese takeaway order.

It will now be up to crisp fans to choose a winner, with every pack purchased counting as one vote.

The flavour that sells the most by November 30 will be given a permanent place in the Walkers family, with the winner given up to £500,000, based on five per cent of overall sales.

Becky said she was 'initially apprehensive' when her opponent's flavour was announced, but said: "I felt like I had the edge with my unique flavour.

"It’s cheesy, it’s sweet and with a little chilli heat, you can’t go wrong."

If she manages to secure the win, Becky hopes to share her new found wealth.

She said: "I’d love to set myself and my family up for life.

"I’ve always been entrepreneurial so I really like the idea of starting up my own business.

"I’d invest some and then eventually buy my own house, and of course, a few luxuries.

"I’ve never been abroad so would be incredible to travel a little. I’m all about life experiences, exploring the outdoors and having fun.

"I would also probably get myself a more reliable car as mine is 14 years old now, and I think her time is slowly approaching, but who knows where the money could take me."
