How to Make It
In a small saucepan, combine ¼ cup water with the sugar, vinegar, garlic, chiles, and a large pinch of salt. Bring to a simmer over medium heat and stir to dissolve the sugar.
In a small bowl, dissolve the arrowroot in the remaining ¼ cup water.
When the sugar is dissolved, whisk the arrowroot mixture into the pot. Stir continuously over medium heat until the sauce begins to thicken, about 2 minutes. Remove from the heat and let cool slightly before serving.
