First Step: Peel and Slice the Plantains
Begin by trimming off the ends of the green plantains. Make shallow, lengthwise cuts through the thick skin without cutting the flesh underneath. This technique allows for easy peeling while keeping the plantains intact. Peel away the skin and slice each plantain into 1-inch thick rounds (or 2-inch chunks if preferred), ensuring uniform pieces for even frying.

Second Step: Heat and Prepare Oil
Pour the vegetable or canola oil into a large skillet or deep pan, enough to submerge the plantain slices halfway. Warm the oil over medium heat to approximately 350°F (175°C). Starting with warm oil gently cooks plantains and prevents too harsh a crust forming.

Third Step: Fry Plantain Slices First Time
Fry the plantain slices in batches without crowding the pan. Cook each batch for about 4 to 5 minutes per side, until they turn golden and are tender but not crispy. Remove the fried plantains and place them on paper towels to drain excess oil.

Fourth Step: Flatten the Fried Plantains
Using a tostonera (plantain press), flat plate, glass, or any pressing tool, gently flatten each fried plantain piece to about half its original thickness. Be careful to keep them intact to avoid breaking.

Fifth Step: Soak Flattened Plantains
Optionally soak the flattened plantains in a mixture of 2 cups water, minced garlic, kosher salt, and lime juice for 4 to 10 seconds. This step adds flavor, prevents browning, and creates steam when fried again, improving crispness. After soaking, pat the pieces dry thoroughly using paper towels to avoid oil splatter and sogginess.

Sixth Step: Second Fry for Crispiness
Heat the oil to medium-high or maintain at 350°F (175°C). Fry the flattened plantains for 1 to 5 minutes per side depending on thickness, until they achieve a crispy, golden brown exterior. Remove and drain on paper towels.

Final Step: Seasoning and Serving
Immediately sprinkle hot tostones with salt and serve warm. They pair perfectly with dipping sauces such as garlic mojo, mojo verde, mayo-ketchup, or fresh guacamole. This recipe can be adapted for healthier cooking by air frying, reducing salt, and customizing dipping options to fit dietary preferences.
