Add all the ingredients into a blender, except the 5-6 stalks lemongrass, and without the chicken of course.
Blend until you get a paste, add splash of water if too dry.
Marinade the chicken on both side for 1 hour to 24 hours. I marinated the night before.
Preheat oven to 200C.
Place lemongrass on the base of baking sheet.
Place chicken on top of lemongrass.
Bake for 20 mins then use a spoon to wipe/scrape off the thick lemongrass paste that is still on the chicken skin.
Continue baking for another 30-35 minutes or until cooked.
Garnish with lime wedges and serve with Nam Jin Jaew
