a smoker box or small foil pan; 1 cup hickory or apple wood chips
Whisk together the soy sauce, balsamic, sugar, crushed garlic and juice of 2 lemons in a bowl until the sugar is dissolved. Add the chicken and marinade to a resealable plastic bag and marinate in the fridge for 3 hours.
Take the chicken out of the marinade and dry off. Sprinkle with salt and pepper.
Preheat a grill to high heat. Place a large cast-iron skillet on one side of the grill. Place a smoker box or foil pan with wood chips on the grill.
Once the smoker has begun to produce smoke, liberally oil the grill grates and place the chicken on the grates. (We are just looking for a quick hard sear on both sides to get that char flavor. The goal is to finish cooking in the creamy, smoky corn.)
Add the butter to the skillet along with the Fresnos, poblanos, onions and remaining 3 whole cloves garlic. Saute until the onions are translucent and chiles are tender, about 10 minutes. Deglaze with the sherry and add the fresh corn, squash, zucchini, cream, 1/2 cup Parmesan and half of the stock. Season to taste.
Add the chicken to the skillet and lower the grill to medium. Close the lid and smoke the skillet over medium heat, playing with the position of the skillet to ensure you get the liquid to simmer ever so slightly, until the chicken hits 160 to 165 degrees F, 10 to 15 minutes. Take the skillet off the grill and pour in a little chicken stock if the sauce is very thick. Add the remaining lemon juice on top and garnish with the cilantro, remaining 2 tablespoons Parmesan and crushed corn nuts.
