Famed for his super-fast 15-minute meals, TV chef Jamie Oliver yesterday showed just how quick he is in the kitchen by setting a new world record for most chillies chopped in thirty seconds.

In a showdown with his mentor, Italian chef Gennaro Contaldo, Jamie managed to slice and dice 10 chillies in the allotted time, beating his one-time tutor's display by four.

Not be outdone by his former apprentice, Gennaro later made a successful attempt at the Guinness World Records title for most ravioli made in two minutes.

The pasta master managed to fold an impressive 24 parcels, beating the existing record of 22 originally set by his friend and fellow Italian Gino D'Acampo.

The attempts took place at Jamie's east London offices during the launch of Jamie's new YouTube channel Food Tube.

The channel, which launched with a live show yesterday, features recipes from around the world along with Q&A sessions with top chefs and viewers, with more food-based world record bids planned for future shows.

On hand to oversee yesterday's record attempts was official adjudicator Anna Orford, who was joined by Marcus Butler and Alfie Deyes from Guinness World Records: OMG!

Speaking after his supreme display of knife handling, Jamie said: "I've loved Guinness World Records since I was a little kid - loved it, loved it, loved it. You know, I used to watch Record Breakers on TV back in the day so it means a lot to set this record."

Jamie's chilli chopping feat will be available to watch later today on Food Tube, while you'll be able to watch Gennaro's record-breaking ravioli-making master class on The Record Slam show with Marcus and Alfie on Guinness World Records: OMG! next week.
