Tostones is a traditional side dish that's popular throughout Latin America and the Caribbean, especially in Puerto Rico. Unlike platanos fritos, where only ripe plantains are used, tostones are made with unripe, hard, very green plantains. They are sliced into pieces, fried on each side, then smashed or flattened and deep-fried one more time until they become golden.

Once prepared, the tostones are sprinkled with sea salt and served as a side dish to various dishes. They are often served with garlic mojo sauce (mojo de ajo), either on top of the tostones, or on the side as a dip.
