Kǎo Hóng Shǔ — Roasted Sweet Potato

The Story

When autumn arrives in China, the smell of roasting sweet potatoes fills the streets. Vendors push carts fitted with oil-drum ovens, slow-roasting sweet potatoes over hot stones or coals until the sugars caramelize and the skin chars. This is one of China’s most universal street foods — it transcends region, class, and age. The tradition dates back centuries, and the sight of sweet potato smoke rising on a cold evening is pure nostalgia for almost every Chinese person.

What to Expect

A vendor pulls a blackened, slightly collapsed sweet potato from the oven and wraps it in a paper bag. Peel back the charred skin and inside is a deep orange, almost translucent flesh that’s so naturally sweet it tastes like it’s been glazed with honey. The texture is creamy and melt-in-your-mouth. Steam rises from the center. It’s incredibly simple and incredibly satisfying — nature’s dessert.

Tips

The best sweet potatoes are the ones with dark, caramelized juice leaking from the skin — that means they’re perfectly roasted. Sold by weight, so the vendor will weigh it for you. This is the ultimate zero-allergen, zero-additive Chinese street food. Available everywhere from October through March.
