How to Make It
In a large bowl, combine the semolina flour with 2 cups of water. Stir in the shrimp, onion, parsley and garlic. Season with kosher salt.
In a large cast-iron skillet, heat 1 inch of olive oil to 350°. Line a baking sheet with paper towels. Working in batches of 4, add about 1/4 cup of batter at a time to the hot oil, stirring the batter in between each scoop to make sure the liquid does not settle on top. Fry the tortillitas, turning once, until golden, about 4 to 5 minutes. Transfer to the paper towels and season with sea salt. Repeat and serve.
