Wash the hawthorn berries (or other fruits) thoroughly and pat them dry.
Skewer the fruits onto bamboo sticks, leaving a small gap between each fruit.
In a saucepan, combine sugar and water. Heat over medium heat until the sugar dissolves and the mixture starts bubbling.
Continue to cook the sugar mixture until it reaches a light amber color and is thick enough to form strands when drizzled from a spoon.
Quickly dip each fruit skewer into the hot sugar syrup, rotating to coat evenly.
Place the coated skewers on a parchment-lined baking sheet or a wire rack to cool and harden.
Serve the Tanghulu once the sugary coating has hardened completely.
