Roasted sweet potato is a popular winter street food in East Asia and parts of Southeast Asia.

01Regions

China, Hong Kong, and Taiwan

In China, yellow-fleshed sweet potatoes are roasted in a large iron drum and sold as street food during winter. They are called kǎo-báishǔ (烤白薯; "roasted sweet potato") in northern China, wui faan syu (煨番薯) in Cantonese-speaking regions, and kǎo-dìguā (烤地瓜) in Taiwan and Northeast China, as the name of sweet potatoes themselves varies across the sinophone world.

In 2021, Hong Kong chef Lucas Sin went viral for posting about a traditional Chinese method of roasting sweet potatoes, where the potato is first frozen before being roasted until caramelized sugars bleed through the skin.

Korea

Sweet potatoes roasted in drum cans, called gun-goguma (군고구마), are popular in both North and South Korea. The food is sold from late autumn to winter by vendors wearing ushanka, which is sometimes referred to as "roasted sweet potato vendor hat" or "roasted chestnut vendor hat". Although any type of goguma (sweet potato) can be roasted, softer, moist varieties such as hobak-goguma (pumpkin sweet potato) are preferred over firmer, floury varieties such as bam-goguma ("chestnut sweet potato") for roasting.

In South Korea, roasted sweet potatoes are dried to make gun-goguma-mallaengi (군고구마 말랭이) and frozen to make ice-gun-goguma (아이스 군고구마). Although gun-goguma has traditionally been a winter food, gun-goguma ice cream and gun-goguma smoothies are nowadays enjoyed in summer.

Japan

In Japan, a similar street food is called ishi yaki-imo (石焼き芋; "roasted sweet potato in heat stones") and sold from trucks during the winter.

Northern Vietnam

Roasted sweet potato (khoai lang nướng) is a popular winter street food in Hanoi and Northern Vietnam.
