Instructions
- Step 1: Peel and cut 4 medium green plantains into 2-inch pieces. Place them in 4 cups water with 1 tsp salt in a large pot, bring to a boil, and cook uncovered for 20-25 minutes until plantains are very tender.
- Step 2: Drain the plantains and return to the pot. Mash with 3 tbsp butter and 1/2 tsp salt until smooth and creamy, adding a few tablespoons of cooking water if needed to loosen the texture.
- Step 3: Heat 2 tbsp olive oil in a skillet over medium heat. Add 1 large thinly sliced red onion and sauté for 5 minutes until soft and translucent.
- Step 4: Stir in 1/2 tsp red chili flakes, 1 tbsp white vinegar, and 1/4 tsp black pepper. Cook for another 2 minutes until the onions are glossy and tangy.
- Step 5: Serve the mangú hot, topped generously with the sautéed spicy red onions.
