In the back room of Muth's Candies in Louisville, Ky., Jonathon Skaggs and Bobby Masterson are busy dipping marshmallows into a copper pot.
The pot is filled with a top-secret hot caramel mixture. Skaggs and Masterson tap the excess golden caramel off each candy before placing it on a board to cool.
Masterson says it's a rhythm repeated hundreds of times each day.
"They're good ... they're a big-time seller in here in Kentucky, especially right here in Louisville," Masterson says. "There's a lot of people that come and get 'em."
