Add enough oil to 10-inch skillet to reach 1/2 inch depth. Heat the oil over medium heat to 350 degrees. Add the plantains.
Cook for 2 to 3 minutes or until light golden brown on one side. Turn; cook 1 minute longer, until light golden brown. Remove to paper towels.
Using a glass with a flat bottom, very lightly flatten the partially fried plantains. Return to the oil and fry until deep golden brown and tender inside.
Sprinkle lightly with salt. Meanwhile, in a small bowl, mix the remaining ingredients. Drizzle over the plantains or serve as a dip.
