Tanghulu (Chinese Candied Fruit)

Method

1. 1Wash 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.
2. 2Thread 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.
3. 3Line 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.
4. 4Add 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.
5. 5Cook 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.
6. 6Remove 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.
7. 7Wait 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.
