10 won bread

10 won bread (Korean: 십원빵), also sometimes called 10 won waffle^[1] or sibwonppang,^[2] is a South Korean street food that was first sold in Gyeongju in 2019. It is a bread or waffle in the shape of a South Korean 10 won coin that contains stretchy mozzarella cheese.

The bread has inspired a number of variations in various cities across South Korea, including 50 won bread (in Jeonju), 100 won bread (in Tongyeong), and 500 won bread (in Seoul's Sinsa-dong).^[3] In 2022, it spread to Japan as 10 yen bread.^[4]
