An apple a day keeps the doctor away, but most of us would not eat that apple if it was ugly. When bruised or mushy, ugly fruits and vegetables are discarded at the processing stage of the supply chain before even making it to the supermarket. But does this mean that they aren't as nutritious or taste as good? Foodies Shu Hao and Joe are both guilty of judging produce by their looks. To get them to see the beauty in the ugly, host Chef Isaac Henry leads them to Mobile Kaybie, a van that goes around different neighbourhoods in Singapore to distribute rescued produce for free! The trio also heads to a laboratory to check if blemished produce are just as safe and nutritious to eat as perfect looking ones. Then, they learn how to showcase the culinary possibilities made with ugly produce at an eatery. How will Shu Hao and Joe cope when tasked to cook with as many ugly fruits and vegetables as possible in our zero waste cook-off?
