They Hired an Expert on Dalgona Candies
To make as many Dalgona Candies as they did for the challenge, the show had to bring in a Dalgona expert to churn as many of the candies as possible. Not only did they make hundreds of candies, but every actor had a prop team assigned to them that would replace the candy whenever it began to melt or if the camera crew needed a new candy for a different angle. And the actors claimed that licking the candy to get the shape out without breaking it was a real challenge.
