TECHNIQUE
LETS ROCK THE PEANUT SAUCE
Heat ¼ cup oil in a medium saucepan over medium heat. Stir in Blue Elephant red curry paste, combine until simmering. Now, whisk in coconut milk until simmering resumes, then introduce heavy cream, peanut butter, sugar, and remaining oil. Be sure to continue whisking until all ingredients are dissolved and combined. Continue to cook and whisk until sauce coats the spoon. Remove from heat and stir in vinegar; season with salt.
LETS PREPARE THE CHICKEN
Combine brown sugar, mirin, soy sauce, and vinegar in a small saucepan. Transfer 1/2 cup mixture to a large mixing bowl. Slice chicken thighs lengthwise, about 1 inch thick, then add to the marinade in the bowl. Chill for 30 minutes or up to 8 hours.
Add remaining marinade to a simmer over medium-high heat and cook until reduced by half and thick like syrup.
Prepare a grill for medium-high direct heat on one side, indirect on the other. Skewer chicken onto 6–8 skewers, folding and bunching the meat together to make one continuous shape on each skewer. Grill chicken first over direct heat, rotating after two minutes until browned and slightly charred.
Move chicken to cooler side of grill and continue to cook, slathering the chicken skewers with the glaze until cooked through. Serve on a platter with a banana leaf and the red curry peanut sauce.
