Chicken Kebab with apple flavored bbq sauce

Hi,


I ate these kebabs in Seoul, Bucheon and they were amazing. They were at a street vendor and it was fried chicken on a stick, there was flour that was fried on the chicken and the sauce was sweet with a hint of apple. Does anyone know what these are called in Korean and if I can find them in Busan?


Please help.

I didn't find the right solution from the Internet.
