Tanghulu originated in northern China during the Qing dynasty as a winter street snack. Vendors would thread candied hawthorn berries onto sticks, and the bright, glossy sugar coating became a visual hallmark of festive markets and fairs.

While the classic version uses hawthorn berries, many regions substitute strawberries, grapes, or even small apples. In some northern towns, a thin layer of sesame seeds is rolled over the hardened sugar for extra texture.

Tanghulu is typically displayed on bamboo skewers in rows on a tray, allowing customers to pick them up by the stick. They are eaten as a sweet treat during Lunar New Year, winter markets, and temple fairs.

Tanghulu is especially popular during the winter months, Lunar New Year, and local temple festivals where street vendors set up stalls. Its bright red sugar coating symbolizes good luck and warmth.

The contrast between the crisp, glass‑like sugar shell and the juicy, fresh fruit inside creates a unique texture that is both crunchy and refreshing—something rarely found in other Chinese street foods.

Common errors include stirring the syrup after it starts boiling (causing crystallization), using plastic containers that melt in the microwave, and dipping fruit that isn’t completely dry, which leads to a soggy coating.

The stovetop method allows precise temperature control to reach the hard‑crack stage safely. Microwaves heat unevenly and can cause plastic containers to melt, creating dangerous burns and chemical exposure.

Tanghulu is best served fresh. If you must make it ahead, keep it in an airtight container at room temperature for up to one hour; avoid refrigeration as humidity will make the sugar shell sticky.

The syrup should be a clear, amber liquid that, when a drop is placed in cold water, forms a hard, glass‑like thread that snaps cleanly. The surface should be glossy, not grainy.

When the candy thermometer reads 149 °C (300 °F) and the syrup has a deep amber color, it has reached the hard‑crack stage. A test drop in cold water that hardens instantly confirms readiness.
