01 - Wash all fruit thoroughly and dry each piece completely to prevent the sugar coating from seizing.
02 - Thread 2 strawberries, 2 grapes, and 1 mandarin segment (or cherry tomato) onto each bamboo skewer, alternating fruit for color and flavor contrast.
03 - Line a baking sheet with parchment paper or set a greased wire rack nearby for finished skewers.
04 - Combine granulated sugar, water, and light corn syrup (if using) in a medium saucepan. Stir to dissolve sugar, then bring to a boil over medium-high heat without further stirring.
05 - Cook syrup until it reaches 300°F (hard crack stage) on a candy thermometer. If no thermometer is available, test readiness by dropping a small amount of syrup into cold water— it should harden and crack immediately.
06 - Quickly and carefully dip each fruit skewer into the hot syrup, rotating for even coverage. Allow excess syrup to drip off, then transfer to the prepared baking sheet or rack.
07 - Let the skewers cool undisturbed for about 5 minutes until the sugar shell hardens and turns crisp. Serve immediately for optimal crunch.
