Make the mofongo: Preheat the oven to 375°F (190°C). Grease a standard-size 6-cup muffin tin with nonstick spray.
2. Step
Pour 1–2 inches of vegetable oil into a pot. Heat over medium heat until the oil temperature reaches 350°F (180°C).
3. Step
Peel the plantains and cut into 1-inch pieces. Working in batches, add the plantains to the hot oil and fry for 2 minutes, or until the centers are soft. Remove from the pot and transfer to a paper towel–lined plate to drain while you repeat with the remaining plantains. Let cool for 15 minutes.
4. Step
Transfer the plantains to a mortar and pestle (also known as a pilón),and add the ground pork rinds, garlic, salt, and pepper. Mash together until fully incorporated, 5–8 minutes. If needed, remove the plantain mixture from the pilón and mix with your hands.
5. Step
Roll the plantain mixture into 6 balls. Place a ball into the center of each prepared muffin cup and press evenly against the bottom and up the sides to make a cup.
6. Step
Bake the mofongo cups for 20–25 minutes, or until golden brown. Remove from the oven and let cool to room temperature, about 30 minutes, then remove from the muffin tin.
7. Step
Meanwhile, make the shrimp sauce. Heat the olive oil in a medium pan over medium-low heat. Add the onion, garlic, and red bell pepper, and cook, stirring occasionally, until softened, about 4 minutes. Add the tomatoes, sofrito, adobo sauce, paprika, and coriander, and stir until combined and the mixture begins to deepen in color, 1 minute.
8. Step
Increase the heat to medium-high heat. Immediately add the white wine and simmer for 20 seconds. Stir in the water and simmer for another 4–6 minutes, until slightly reduced.
9. Step
Add the salt and shrimp. Cover and cook until the shrimp turn pink, about 3 minutes.
10. Step
Fill the mofongo cups with the warm shrimp and sauce. Garnish with cilantro, then serve.
