Heat a large grill pan over medium-high heat and add butter, coating the pan. Place the corn on the grill pan and char the kernels, turning occasionally until evenly browned. Remove the corn from the cob with a knife and set aside. (You can also grill the corn outdoors if preferred.)
4 large ears of corn, 3 tbsps. (42 g) butter
Heat a dry cast iron skillet over medium-high heat. Place the prepared shrimp on a tray and brush one side with melted butter. Generously season that side with blackened seasoning. Place the seasoned side down in the skillet and cook for about 2 minutes, or until blackened. Flip and cook until opaque. Keep warm.
20 extra large shrimp (prawns), 4 tbsps. (57 g) butter, Blackened seasoning
Cook the fettuccine according to package directions. Before draining, reserve 1 cup (240 ml) of pasta water. Drain and set aside.
12 oz. (340 g) dry fettuccine pasta
In a large sauté pan over medium heat, melt the butter. Add the diced onion and cook until softened, about 5 minutes. Stir in the garlic and cook for another 30 seconds.
2 tbsps. (28 g) butter, ½ cup (75 g) diced yellow onion, 2 tsps. (6 g) minced garlic
Add the flour and stir until it’s fully incorporated. Cook for 1 minute to remove the raw flour taste.
1 tbsp. (8 g) all-purpose flour
Add the reserved corn kernels, water, heavy cream, and sugar. Simmer for about 2 minutes, or until slightly thickened. (Note: the sauce will be light—not heavily creamy.)
2 cups (320 g) cooked corn kernels , ½ cup (120 ml) water, ¼ cup (60 ml) heavy cream, 1 tsp. (4 g) granulated sugar
Add the cooked fettuccine to the sauce and toss to coat. Stir in the Parmesan, basil, lemon juice, and salt and pepper to taste. If needed, loosen the sauce with a splash of the reserved pasta water.
½ cup (50 g) finely shredded Parmesan cheese, ¼ cup (10 g) thinly sliced fresh basil, juice of ½ a lemon, salt and pepper to taste, reserved pasta water
Divide the pasta among plates or bowls and top each with shrimp. Serve immediately.
