Tanghulu Recipe: Glassy Candied Strawberry Skewers
This tanghulu recipe makes 6 glassy candied strawberry skewers in about 45 minutes: dry the fruit well, cook sugar syrup to the hard-crack stage (300 to 310°F), dip, and let the shell set for 2 to 3 minutes. Tanghulu is a traditional Chinese street snack, first made with hawthorn berries, and strawberries, grapes and mandarin segments all work at home.
Quick answer
Air-dry 18 strawberries for 20 minutes and thread 3 per skewer. Boil 1 cup sugar, 1/2 cup water and 1 tbsp light corn syrup without stirring until a candy thermometer reads 300 to 310°F. Dip each skewer, let the excess drip off and set on parchment for 2 to 3 minutes. Eat within a few hours. About 60 calories per skewer.

Tanghulu Recipe Ingredients
- 1 pint strawberries (about 2 cups, 18 berries), washed and completely dried
- 1 cup granulated sugar
- 1/2 cup water
- 1 tablespoon light corn syrup
- 6 wooden or bamboo skewers, 6 to 8 inches
How to Make Tanghulu
- Rinse the strawberries under running water, pat them dry with a towel, then let them air-dry on a clean towel for 20 minutes. Any moisture left on the fruit makes hot syrup spatter and stops the shell from setting.
- Thread 3 strawberries onto each skewer, leaving 2 to 3 inches bare as a handle. Line a baking sheet with parchment and set it next to the stove.
- Put the sugar, water and corn syrup in a small, heavy saucepan over medium heat. Swirl the pan until the sugar dissolves; once it bubbles, do not stir.
- Clip on a candy thermometer and cook, undisturbed, until the syrup reaches 300 to 310°F (hard-crack stage), about 10 to 12 minutes. Take the pan off the heat right away.
- Keeping your hand well back, tilt the pan and dip one skewer at a time, turning it to coat the fruit thinly. Let the excess drip back for a second or two.
- Stand each skewer on the parchment and leave it for 2 to 3 minutes until the shell is hard and clear. If the syrup thickens before you finish, warm it briefly over low heat.

Estimated from USDA FoodData Central: raw strawberries (FDC 167762, 288 g per pint), granulated sugar (169655) and light corn syrup (168837). Only about one third of the syrup ends up on the fruit; the rest stays in the pan, so one third of the sugar and corn syrup is counted. This is an estimate and varies with how thickly you coat.
Why This Tanghulu Recipe Works
At the hard-crack stage, 300 to 310°F, almost all the water has boiled out of the syrup. What is left cools into a brittle, glass-like candy rather than a soft or sticky one. Stop below 300°F and the coating stays tacky; go much past 310°F and the sugar starts to brown and turn bitter. That is why a candy thermometer matters for any tanghulu recipe.
The tablespoon of corn syrup is an interfering agent: it gets in the way of sugar molecules lining up into crystals, so the shell stays clear instead of turning grainy and white. Not stirring once the syrup boils does the same job, because a spoon can start crystals forming.
Working With Hot Sugar Safely
Hard-crack syrup is far hotter than boiling water and sticks to skin, so set up before you start: keep children and pets out of the kitchen, use a long-handled pan and long skewers, and never touch the coating to test it. If syrup lands on skin, hold the area under cool (not ice-cold) running water for about 10 minutes, as the Mayo Clinic advises for minor burns, and get medical help for anything larger than a small spot.
Best Fruit for Candied Strawberries and Other Tanghulu
| Fruit | How to prepare it | Notes |
|---|---|---|
| Strawberries | Hull or leave the tops on; dry completely | The classic choice for candied strawberries |
| Seedless grapes | Pull off stems; dry well | Firm skins give a very clean shell |
| Mandarin segments | Peel and separate; let the surface dry | Handle gently; the skins tear easily |
| Blueberries | Thread 4 to 5 per skewer | Small berries need a quick dip |
Rinse all fruit under running water and dry it well; the FDA recommends running water, not soap. Wet fruit is the most common reason sugar coated fruit turns out sticky or spatters in the pan.
Common Tanghulu Recipe Mistakes
- Dipping damp fruit. Moisture makes the syrup spit and keeps the shell from hardening.
- Stirring the boiling syrup. It encourages crystals, so the coating turns cloudy and grainy.
- Pulling the syrup too early. Below 300°F the coating stays soft and chewy.
- Coating too thickly. A thin layer snaps cleanly; a thick one is hard to bite.
- Making it too far ahead. The shell softens within a few hours.
Serving and Storing Candied Strawberries
Tanghulu is a same-day treat. The sugar shell draws moisture from the air and from the fruit, so even a good batch turns sticky within a few hours at room temperature, and the fridge makes it worse because of condensation. Make it within an hour or two of serving. It looks striking on a dessert table next to mini pumpkin cheesecakes or a plate of gulab jamun.
Tanghulu Recipe FAQ
Do I need a candy thermometer for this tanghulu recipe?
It is strongly recommended. The hard-crack window is narrow. Without one, drop a little syrup into ice water: it should form hard threads that snap, not bend.
Why is my tanghulu sticky instead of hard?
The syrup most likely did not reach 300°F, or the fruit was damp. Cook the syrup a little longer and dry the fruit for at least 20 minutes.
Can I make tanghulu without corn syrup?
Yes. A teaspoon of lemon juice also helps stop crystals forming, though corn syrup gives a slightly more reliable, glassy shell.
Can I make candied strawberries ahead of time?
Not by much. Eat them within a few hours; the shell softens as it absorbs moisture.
Is tanghulu safe to make with kids?
Kids can help wash and thread the fruit, but an adult should handle the hot syrup and the dipping, and children should stay away from the stove.
