Separate the legs from each quail. Cut out their backs and flatten the breasts with the palm of your hand. To make quail easier to serve with rice, I recommend deboning the breasts.
Remove the tough outer layers of lemongrass and mince the tender lower third of the stalk. Your knife shouldn’t have to work too hard to cut into the tender part. Although the outer layers are edible, they’re too woody to eat.
Place minced lemongrass in a medium mixing bowl along with the remaining marinade ingredients. Add quail legs and breasts, cover, and marinate for at least 30 minutes, but no longer than eight hours. Stir it halfway through marinating.
In a bowl, combine sauce ingredients and set aside. When ready to cook the quail, prepare the grill for medium-high heat cooking. Remove the quail legs and breasts from the marinade and lightly coat them with oil. Grill skin-side down first until it’s golden brown, flip, and cook through on the other side, about 10-15 minutes total.
Serve quail with hot white rice, lettuce, tomato and cucumber. Drizzle salad and rice with sauce to taste.
