Gordon Ramsay offered prisoner job on the spot after what he did when chef visited

It takes a lot to impress Gordon Ramsay, but the celebrity chef was left starstruck on a visit to a British prison back in the 2000s.

The Michelin star restaurant owner has known to be very hard on those working in his kitchens (who could forget that idiot sandwich moment?), but he had nothing but compliments for one of the prison chefs who appeared on The F-Word - a reality cooking series that ran for five seasons from 2005.

Ramsay, who has had to put up with a lot during his TV appearances including eating a cheese filled with maggots, visited HMP Doncaster as part of the show and chatted with some of the chefs who cook for prisoners every day, which is where he met Kieron Tarff for the first time.

The TV chef may well have been fearing the worst when going into the prison, although nothing can compare to the worst meal he's ever eaten, but he ended up offering young Kieron a job after challenging him to a competition.

In the episode, Gordon asks him for a race at chopping up an onion and despite his vast experience and training, it was the young prisoner who came out on top in the race.

Clearly impressed by Kieron's speed, Gordon offers him a job before reassuring him that he is serious, asking him when he will be released from prison.

Who's cutting onions?

Professional chefs are well-known for their speed and precision when it comes to chopping veg, so there's no doubting that Kieron had a lot of talent in the kitchen, but it remains unclear what happened to him after the show.

He mentions during the episode that he was scheduled to be released in 2007, but nobody seems to know where he ended up after coming out - but at least he will always have the video evidence of beating perhaps the most recognised chef in history in a cooking challenge.

Meanwhile, the celebrity has identified some of the red flags you should be aware of when heading out for your next meal.

He said: "Specials are there to disappear throughout the evening. When they list 10 specials, that's not special."

Terminology such as 'world's best', 'famous' or 'best in the country' are worrying signs for the award-winning chef, who also advises on asking what yesterday's soup of the day was before learning today's, amid fears that it could well be a 'soup of the month'.
