In Voices this week, we meet the Auckland couple who smashed the Guinness World Record for baking the world's biggest lamington.

New Zealand's latest Guinness World Record holders know the sweet taste of success thanks to a massive lamington, weighing more than 2700 kilograms, topped with 200 kilograms of jam, 200 kilograms of coconut and literally buckets of chocolate sauce.

2020 has been a rollercoaster of a year for Farhan and Zeenat Sattar, co-owners of Creative Edge Food Company, a bespoke wholesale bakery that supplies goods to cafes around the country.

At the beginning of the year, Farhan Sattar set himself a goal.

"He goes, I want creative to be known internationally," said Zeenat, "I'm like, okay. We didn't know how that would happen."
