Prepare Your Fruit
Wash all fruit thoroughly in cold water. Pat completely dry with paper towels - any moisture will prevent the coating from adhering properly. Thread 1-3 pieces of fruit onto wooden skewers and arrange on a clean plate near your workspace.Set Up Ice Bath
Prepare a large bowl filled with ice water and place it next to your cooking area. This will be essential for setting the candy coating immediately after dipping.Make Sugar Syrup
In a stainless steel pot, combine sugar and water. Do not stir the mixture once heating begins. Place over medium heat and cook for 15-20 minutes until the mixture reaches exactly 300°F on a candy thermometer (hard crack stage).Coat the Fruit
Working quickly, dip each fruit skewer into the hot sugar syrup, rotating to coat completely. Immediately plunge the coated fruit into the ice water bath and hold for 10-15 seconds until the coating hardens.Serve Immediately
Place the finished tanghulu on a parchment-lined baking sheet. Repeat with remaining fruit skewers. Serve immediately for the best crispy texture, as the coating will soften over time.
