1. Preheat oven to 350 degrees. Line a baking sheet with parchment paper.

2. In a small bowl, combine flour and ginger with a whisk. Melt butter in a small saucepan over medium heat. Add sugar and golden syrup; cook, stirring with a wooden spoon, until sugar is dissolved. Remove from heat; stir in flour mixture.

3. Using a 2/3-ounce ice cream scoop, drop three level scoops of batter onto prepared baking sheets, about 2 inches apart. Bake until flat and golden brown, about 10 minutes, rotating halfway through.

4. Remove from oven and let cookies cool just slightly until firm, about 2 minutes; place each cookie over an inverted drinking glass or wrap around the handle of a whisk, using your hands to press and gently shape. Let set 30 seconds. Transfer to a wire rack to cool. Repeat process with remaining batter.
