Prepare the Sauce - In a saucepan mix ¼ cup of coconut cream with cornstarch, until it is smooth and uniform. Heat over low heat, add the remaining ingredients except the green onions. Stir until sugar and salt are dissolved, turn off heat and stir in green onion. Reserve half of the sauce for serving.
Grilling the Corn - Preheat grill to 450ºF. Lightly coat each corn with coconut sauce. Place the corn on the grill and cover. Brush corn with coconut sauce and turn every 5 minutes until cooked or when the kernels become brown.
