Gregg Wallace of Celebrity MasterChef found himself startled on Monday when one of the contestants committed a significant mistake.

In the fifth episode of the season, four hopefuls fiercely competed for just three coveted spots in the quarter-finals. Among them were comedian Eshaan Akbar, actresses Danielle Harold and Rochenda Sandall, and athlete-slash-Gladiator Harry Aikines-Aryeetey, each facing a trio of culinary challenges.

The drama unfolded during the initial task, known as the Paris Challenge. In this round, the celebrities were paired up and tasked with creating identical dishes. However, Harry encountered trouble while trying to mimic Rochenda’s samosas, as only Rochenda had access to the recipe.

The mishap occurred when Harry, in the heat of the moment, neglected to close the oven door completely. This detail did not escape the notice of Gregg’s co-presenter, John Torode, who remarked, “Harry has left his oven door open.”

Harry was attempting to replicate Rochenda’s samosas – with the cruel twist that only she had the recipe – when he failed to close the oven door fully.

Gregg’s co-presenter John Torode, 59, observed: ‘Harry has left his oven door open.’ 

Meanwhile, Gregg, 59, added in a confessional: ‘Now, if there’s anyone big and strong enough to shut an oven door, it’s Harry! Now it’s touch and go whether they’ll cook or not.’

Despite the blunder, both Gregg and John were pleased when Harry and Rochenda presented their dishes.

Gregg said: ‘I think they look brilliant, I’m really impressed,’ and John added: ‘You’ve done remarkably well here, they do look very similar.’

However, Gregg scolded Harry: ‘Slight overcooking on the lamb. Not enough cookery on your samosa – you didn’t shut the oven door.’

But, it wasn’t enough to stop the pair heading through to the quarter-finals alongside Danielle Harold, meaning Akbar unfortunately headed home.

The second heat had begun in episode four with an additional celebrity, reality television star Chloe Burrows, but she exited at the end. 

The first heat premiered on August 12 with Craig Doyle, Charlotte Crosby, Edith Bowman, Ian ‘H’ Watkins, and Snoochie Shy.
