For the corn: Add the milk and 2 cups water to a 3- to 4-quart pot and bring to a simmer. Add the butter, salt and sugar and cook until the butter has melted. Add the corn, cover, and cook until tender, about 45 minutes.
Remove the corn from the pot and cool down enough to handle, then cut off the kernels with a knife. (Hint: it will be easier to remove the kernels from the cob if still warm.)
For the red pepper nage: Meanwhile, preheat the oven to 400 degrees F.
Mix together the oil, shallots, garlic, peppers, tomatoes, thyme and salt and white pepper to taste, making sure to coat all the ingredients evenly with the oil.
Lay all the vegetables on a baking sheet and roast for about 20 minutes. Transfer to a blender and mix until smooth.
Heat the heavy cream in a saucepot and bring to a boil. Pour the cream into the vegetable mixture and blend until incorporated. Strain the nage through a fine-mesh strainer.
For the scallops: Heat 1 teaspoon of the grapeseed oil in a saute pan until hot (about 350 degrees F), and then sear the scallops until golden brown on both sides.
Heat the remaining oil in a separate saute pan. Add the garlic and shallots and cook until soft, and then add the corn and cook for a few minutes. Turn down the heat and add the truffles, if using, the chives and tomatoes. Just before serving, add the butter and cook until melted and incorporated. Season with salt and white pepper.
To plate this dish, we use an 8-inch round white plate. First, place a small amount of the corn succotash in the center of the dish. Place the browned scallops directly onto the corn. Finally, spoon a few ounces of the red pepper nage around the corn and serve.
