Heat a stock pot over medium heat. Add the butter and onions.
Sauté the onions for 3-5 minutes until they are translucent.
Add the garlic, salt and pepper, white wine, water, broth, corn, and rice. Stir to combine.
Allow the risotto to cook for 20-25 minutes, stirring occasionally, until the liquids have reduced and thickened, and the rice is tender.
Turn off the heat. Stir in the heavy cream and parmesan. Cover and allow to sit for 10 minutes.
Seared Scallops
Heat a large skillet over medium heat. Melt the butter.
Remove the side muscle from the scallops. Pat them dry and lightly season if desired.
Place the dry scallops into the skillet. Let the first side cook for 2-3 minutes or until you begin to see the side turn opaque white and they easily release from the pan. Flip and cook the second side another 2-3 minutes. They should feel slightly firm but still spring back when touched. Remove from the pan.
Basil Pesto
Add all of the ingredients to a food processor and blend until smooth.
Assembly
Plate your corn risotto. Top the risotto with the scallops. Garnish with basil pesto.
