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 first challenge was a series of kitchen prep tasks. The final task saw Marion, Daniel, Adele and Courtney cut salmon fillets of the correct weight andtheywere given their Top 24 aprons.
Alvin cooked off against Luke Nguyen, chef and owner of Red Lantern in Sydney. Theyboth cooked a Vietnamese banquet of three dishes: Hanoi Crisp Parcels; Hue Pancakes and Barramundi which was wrapped and grilled in a lotus leaf.
The six contestants who won Top 24 spots cooking against Matt Moran were treated to a Masterclass with him in ARIA's kitchen.
