The award-winning chef was a special guest at the final battle between prisoners involved in a City and Guilds Hospitality and Catering course run by Belfast Metropolitan College.

A total of 25 prisoners took part in the competition to produce savoury meals, quiche, chicken-en-croute and sausage roll, as well as mouth-watering sweets including apple and pear crumble, lemon syllabub shortbread and Victoria sponge.

After two heats of the competition, three finalists were selected to compete for the final prize crown, each creating a trio of desserts.

Mr Deane eventually chose a 25-year-old prisoner with a lemon meringue, deconstructed cheesecake and profiterole tower as the winner.

Mark Holmes, head of activities at Maghaberry, said: “We are delighted Michelin-star chef Michael agreed to judge the Maghaberry Bake-Off.

“All of the prisoners who took part in the competition enjoyed the experience and many of them will also come away from the course with a qualification in catering and hospitality.”

He added: “Part of the work of the Northern Ireland Prison Service is to challenge people in our care and support them to change. Encouraging them to live a healthier life-style through vocational skills will also help them when they are released, reducing the risk of re-offending and helping to build a safer community.”

Mr Deane said: “This is the first time I have been in Maghaberry and I have been both surprised and impressed by what I have seen here today.

“Picking a winner was not easy and I want to congratulate everyone who has taken part in what has been a great showcase for the hospitality and catering skills that prisoners are learning here at Maghaberry.”

David Seffen, head of prison programmes at Metropolitan College, said: “We are delighted so many prisoners have taken part in this bake-off event. It is illustrative of the work ethic of prisoners and is testament to the skills and confidence of our catering and hospitality teaching in Maghaberry.

“With the growth in Northern Ireland’s hospitality sector, this is encouraging. It means prisoners will be leaving prison work-ready, which ties in with Belfast Met’s aim of social inclusion, widening participation and helping to reduce reoffending.”
