How to Make It
Cook pasta according to package directions, omitting salt and fat. Scoop out and reserve 1 cup pasta water. Drain pasta; keep warm.
Meanwhile, place 1 1/2 cups corn in a mini food processor (reserve remaining 1/2 cup corn); process until almost smooth, scraping sides as needed. Add milk and cornstarch; pulse until well combined. Set aside.
Melt 1 tablespoon butter in a large skillet over medium-high. Add shrimp; cook until lightly browned and cooked through, about 3 minutes, turning occasionally. Remove shrimp from pan; keep warm.
Melt remaining 1 tablespoon butter in skillet over medium. Add scallions; cook 1 minute, stirring frequently. Add pureed corn mixture, salt, and pepper; cook until thickened, about 1 minute, stirring constantly. Stir in 1/2 cup reserved pasta water and 1/2 cup reserved corn kernels. Add pasta and shrimp; toss gently to coat. Add remaining pasta water as needed to moisten pasta. Sprinkle evenly with parsley and basil.
