To a large container or bowl, add water and soak your skewers for at least 20 minutes.
12 skewers
Cut the chicken thighs into cubes and slice the scallion whites into 2-inch pieces.
1 ½ lb chicken thighs, 20 scallion stalks
In a pot over low heat, add the sugar and oil. Let it melt and caramelize, shaking the pot often so it caramelizes evenly. Resist the urge to stir it with a spatula, as this will cause the sugar to crystallize.
½ cup sugar, ½ tbsp oil
Once caramelized, add the coconut water and stir aggressively. It'll bubble and seize up at first, but keep stirring on low heat until most of the sugar has dissolved back into the liquid. This may take a few minutes. If you're having trouble dissolving the sugar, cover it with a lid for a couple minutes until the sugar has mostly dissolved.
½ cup coconut water
Stir in the smashed garlic cloves, fish sauce and a pinch of salt. Add the black pepper and continue stirring until everything is combined and the sauce has thickened slightly. Remove from heat and set aside ⅓ of the glaze for serving.
3 tablespoons fish sauce, 4 garlic cloves, ¼ tsp black pepper, salt
Skewer the chicken and scallions onto your soaked skewers, alternating them between chicken and scallion. Season the skewers with a little salt.

Preheat your grill on medium low.
Once heated, place your skewers on the grill. Cook one side for 2-3 minutes until lightly seared. Brush the top-facing side with glaze. Flip every 1-2 minutes, brushing on fresh glaze after each flip, until the chicken reaches an internal temperature of 165F and the outside is caramelized and slightly charred. Enjoy with rice and fresh herbs!
