Troy and Heidi Waters will compete for "bragging rights" in a trans-Tasman cook-off this weekend.
The brother and sister pair form the New Zealand junior team representing the country at the Gourmet Pacific Challenge in Auckland.
Though Troy has been in the team four years running, it's a first for Heidi and also the first time the competition has seen siblings competing together.
"We will be competing for bragging rights against the Aussies," Heidi said.
The 22-year-old said she and her brother had been working on a three-course meal that would be served up to some of New Zealand's best chefs.
The pair will have four hours to dish up the meal, with each course having certain requirements.
"We're doing a mushroom cappuccino for the starter," Troy, who is the head chef at Mexico, said.
"It's a soup in a coffee cup topped with savoury cream that looks like foam."
Although happy to disclose the recipe for the starter, the main and dessert would be kept a secret, he said.
"I'd loved to tell you, but the Aussies have spies everywhere."
Chefs receive marks for the taste, flavour and presentation of their food and their skills in the kitchen.
"If your food is good, but you're a cowboy in the kitchen, you can lose marks," Troy said.
The pair have been cooking together since Heidi started working at Okurukuru eight years ago.
"I was already working out there and said to the boss, ‘I want to move up'. He said if I found someone to wash my dishes I could and Heidi was working the next day," 24-year-old Troy said.
Heidi, who is the sous chef at Mexico, said she had learned everything from her brother.
"It's awesome working with him, people think it's strange but it's actually easier cause you know how each other work."
And have they had a bust up in the kitchen?
"Oh yeah," Troy said.
