Peel the plantains and cut them into bite-sized pieces. Place the pieces in a large bowl.
In a small bowl, mix together the cayenne pepper, ground ginger, ground cloves, ground nutmeg, salt, sugar (if using), and minced garlic.
Sprinkle the seasoning mixture over the plantain pieces and toss until they are evenly coated.
Heat the vegetable oil in a deep frying pan or pot over medium-high heat. The oil should be enough to submerge the plantains.
Once the oil is hot, carefully add the seasoned plantain pieces in batches. Fry for about 3-5 minutes, or until they are golden brown and crispy.
Use a slotted spoon to remove the plantains from the oil and drain on paper towels.
Garnish with fresh cilantro or parsley if desired.
Enjoy your meal!
