Japanese Style Chicken and Leek Skewers

Directions

1. Before cooking, soak the wooden skewers in water for 30 minutes. This prevent the skewers from burning when they go on the grill.
2. Add all the ingredients for the sauce (soy sauce, vinegar, sugar, garlic, and ginger) into a small saucepan, and bring it to boil. Once it starts boiling, reduce the heat to low and let the sauce simmer for 20 minutes. The sauce should be thicker and reduced by half; if not, add 1 tablespoon of corn starch, mixed with 1 tablespoon of warm water, to the saucepan.
3. While the sauce is simmering, cut the chicken thighs into 1-inch cubes. Cut the leek in half lengthwise, and chop each half into 1-inch long pieces. Wash the leek thoroughly, as there might be dirt between the layers of the leek. Alternate the chicken and leek on the skewers.
4. Place the skewers on the grill. Cook each side for about 2 minutes, until the chicken thighs are crispy on the outside. Make sure to not overcook the chicken at this step.
5. Every thirty seconds, brush the sauce on the top side of the skewers. Repeat until you brush the sauce 4 to 5 times on each side. When the chicken is cooked thoroughly, remove the skewers from the grill. Before serving, brush the sauce once more. If you want richer flavor, sprinkle 1 tablespoon of toasted sesame seeds on top.
6. If you have leftover sauce, place it in a small serving dish. This can then be used as a dipping sauce during your meal.
7. The sauce has a tendency to remain on the grill, so if you are doing more than one batch of skewers, we recommend cleaning the grill after each batch.
