Soften the butter.

Combine softened butter, coriander, cumin, oregano, ginger, cinnamon, salt, and pepper in a bowl.

Mix the ingredients thoroughly.

Cut four squares of heavy-duty foil.

Place one ear of corn on each foil square.

Spread the butter mixture evenly over each ear of corn.

Wrap the foil tightly around each ear of corn to create a sealed packet.

Preheat grill to medium heat.

Place foil packets on the grill.

Cook, turning frequently, for 15-20 minutes, or until corn is tender.

Carefully open the foil packets to avoid steam burns.

Serve immediately.
