To prepare sauce: Combine oil, coconut aminos (or tamari), brown sugar, thyme, peppercorns, allspice, bay leaves, red chile, scallion, garlic, shallot, Scotch bonnet (or habanero), ginger, nutmeg, salt, lime zest and lime juice in a blender; blend until completely smooth, about 1 minute.
To prepare corn: Heat a clean grill to medium-high heat; rub grates with avocado oil. Rub corn ears lightly with 1 tablespoon avocado oil. Place the corn on the grill; cook, turning occasionally, until the kernels are golden brown and charred on each side, about 5 minutes. Brush the corn with the jerk sauce and continue cooking, flipping and glazing twice more, until the kernels are tender, juicy and lightly charred black and golden brown all over, about 5 minutes more. (Refrigerate the remaining sauce for another use.) Move to a platter and drizzle with olive oil. Garnish with cilantro, if desired.
