Patacones (known as tostones in central america) are twice-fried rounds of green plantain. Fried green plantain (pltano verde) is a starchy and sweet snack and they work great as an appetizer as well. This recipe is easy to follow, though you will want to begin about an hour before you intend to serve them because the plantains need to soak. While you're waiting, prepare a fresh aji amarillo sauce if you don't already have one. This creamy chili pepper sauce is the perfect dip for your patacones.
