Dubbed the ‘punk princess of pastry’, Melbourne-born chef Anna Polyviou made her debut on MasterChef last Monday.

The 36-year-old was in charge of the most difficult and stressful elimination challenge Channel 10 has featured so far.

Polyviou had the three contestants try to remake her award-winning carrot cake, which took her own team of 10 professional pastry chefs more than 30 attempts to perfect.

The recipe was a 12 element, 40 step, three-hour-long kitchen ordeal for MasterChef gals Rose Adam, Jacqui Ackland and Fiona Grindlay.

George Calombaris’ former apprentice, who returned after she won herself a scholarship to London before heading to Paris to train with renowned chocolatier Pierre Herme, introduced the perfect pressure tests.

Fiona was the one sent home on the night, but Anna Polyviou will be coming back for some more bitter-sweet challenges.
