The MasterChef kitchen welcomes 12 emerging home cooks and 12 of MasterChef's most loved past contestants. Together they will share their love of food and compete to become Australia's next MasterChef.

MasterChef 2010 kicked off with the top 50 contestants cooking a BBQ dish of their own choosing.

The contestants each cooked their signature dishes but were judged by their fellow contestants, not the judges. The women tasted the men's dishes and voted for the best three.

The contestants have a huge challenge today, they head to Hatfield House in Hertfordshire where it is revealed they will cook for iconic Chef Heston Blumenthal.

The final 8 head to the Kitchen for their Mystery Box challenge, only to find that there is not challenge today, instead they open their boxes to reveal that they are heading off to London for the week.

Some of the contestants headed to Sake restaurant to learn how to make agedashi tofu and tuna sushi with chef Shaun Presland.
