Instructions

1. Step 1: In a large pot, bring 4 cups water and 1/2 tsp salt to a boil. Add 3 medium peeled and cut green plantains and boil for 20-25 minutes until very tender when pierced with a fork.
2. Step 2: Meanwhile, heat 2 tbsp unsalted butter in a skillet over medium heat. Add 1 medium thinly sliced red onion and sauté for 6-8 minutes until softened and translucent. Stir in 1 tbsp white vinegar and cook an additional 2 minutes until slightly caramelized. Remove from heat and set aside.
3. Step 3: Once plantains are cooked, drain and return to pot. Mash with a potato masher or fork, adding 1/2 tsp salt and 2 tbsp of the cooking water at a time until smooth and creamy.
4. Step 4: In a separate nonstick skillet, heat 2 tbsp vegetable oil over medium heat. Crack 4 large eggs into the pan and fry for 3-4 minutes until whites are set but yolks remain runny, seasoning with 1/4 tsp black pepper.
5. Step 5: Serve the mashed plantains (mangu) topped with the sautéed red onions and fried eggs for a rich and hearty Dominican breakfast.
