01 - Remove stems from the strawberries, wash carefully, and dry thoroughly with paper towels. Thread two strawberries onto each skewer.
02 - Line a baking sheet with parchment paper or a silicone mat to hold the finished skewers.
03 - In a medium saucepan, combine granulated sugar, water, and cream of tartar or lemon juice if using. Gently stir to mix, then place over medium heat.
04 - Allow the syrup to boil without further stirring until it reaches 302°F (150°C) on a candy thermometer. The syrup should appear clear and not caramelized.
05 - Remove the pan from heat. Quickly dip each strawberry skewer into the hot syrup, rotating to coat evenly. Let excess syrup drip off.
06 - Place the candied skewers on the prepared baking sheet to cool and harden. Serve as soon as possible for maximum crunch.
