Bring a large pot of salted water to boil.
In a large skillet, heat the Yellow Onion (1). Saute the Olive Oil (2 tablespoon) and Corn Kernels (3 cup) over medium-high heat, stirring occasionally, until beginning to caramelize, about 5 minutes.
Add the Garlic (1 clove), Sea Salt (1/2 teaspoon), and Cayenne Pepper (1/4 teaspoon). Cook for one minute more, until very fragrant. Remove from the heat.
In a small food processor, puree half of the corn mixture with the Ricotta Cheese (1/2 cup) and 1 Tbsp of Lemon (1). Taste for seasoning and add more salt as necessary. Transfer to a mixing bowl.
Cook theGluten-Free Fettuccine (8 ounce) according to package directions. Reserve 1/4 cup pasta water. Drain and toss immediately with the ricotta mixture, remaining corn, and Fresh Chives (1 tablespoon).
Add some of the cooking liquid to loosen the sauce if necessary. Garnish with the remaining Fresh Chives (1 tablespoon).
