Tanghulu (Chinese Candied Fruit)
Tanghulu has been sold on Beijing streets since the Song dynasty, but most people outside China discovered it through TikTok — where the cracking sound became its own genre. Fresh fruit on a stick, sealed in boiling sugar that sets like glass. Three ingredients. You will probably mess it up the first time. The instructions below exist so you don't.
Ingredients
- 300 gstrawberries
- 200 ggranulated sugar
- 100 mlwater
Method
- Wash the fruit and dry it completely — not mostly dry, bone dry. Press each piece between paper towels. Any water left on the surface will make the sugar seize into a white, grainy crust instead of a clear glass shell.
- Thread 3–4 pieces of fruit onto each bamboo skewer, leaving a small gap between pieces. That gap matters when eating: you can bite cleanly from one piece to the next without shattering the sugar on the piece below.
- Line a baking sheet or plate with parchment paper and set it next to the stove. Fill a large bowl with cold water and a few ice cubes — you'll use this to test the syrup.
- Add the sugar and water to a small, heavy-bottomed saucepan. Stir once just to wet the sugar, then stop. Do not stir again. Stirring introduces air and causes crystallization — you'll end up with something white and chalky instead of glassy and clear. Cook over medium-high heat.
- Cook without touching the syrup until it reaches 300°F (150°C) — the hard-crack stage. No thermometer? Drip a few drops into the ice water. If they form brittle threads that snap when bent, you're there. If they bend instead of snap, cook a little longer.
- Remove the pot from heat. Tilt it to one side and dip each skewer in, rotating slowly to coat evenly. Lift it out, let the excess drip for 2 seconds, then lay flat on the parchment. The coating sets in about 30 seconds.
- Wait at least 10 minutes before eating so the sugar is fully cool and hard. Eat within 2 hours — the fruit's moisture gradually softens the shell from the inside, and by hour three you'll have something sticky rather than crunchy.
FAQ
The syrup didn't reach 300°F (150°C), which is the hard-crack stage. At lower temperatures the sugar stays in the soft-ball or soft-crack range and sets as chewy toffee rather than brittle glass. Use a candy thermometer, or test by dropping a bit of syrup into ice water — it should form threads that snap, not bend. Another cause: wet fruit. Even a thin film of moisture prevents the syrup from bonding properly. Dry the fruit with paper towels until there's no visible dampness.

I weigh every ingredient for tanghulu instead of using cups. Baking is chemistry. An extra tablespoon of strawberries can push this from perfectly balanced to dense and heavy. A $15 scale pays for itself immediately.
