Peel plantains and cut them on a diagonal into 3/4-inch thick slices.

Heat 3/4 cup of oil in a heavy skillet.

Fry the plantain slices in the hot oil until golden brown on both sides.

Remove the fried plantain slices from the skillet and place them on a plate or tray to cool slightly.

Use a spatula to flatten each plantain slice.

Return the flattened plantain slices to the hot oil and fry again until they are crisp and golden brown.

Remove the twice-fried plantain slices from the skillet and drain them on paper towels.

Season the tostones with salt and black pepper.

Keep warm on a serving plate.

In a small bowl, whisk together chopped garlic, sour orange juice, and remaining 1/4 cup of oil to make the mojo sauce.

Dress each serving of tostones with the mojo sauce.

Serve the tostones with mojo immediately.
