Remove the husk from the ears of corn and cut the kernels off. In a nonstick saute pan melt the butter and saute the corn kernels until they cook and have a few brown specks on them.
In a medium saucepan, heat the cream, milk, and half the Sauteed corn kernels over medium heat, stirring occasionally, just until it comes to a boil. Immediately turn off the heat and set aside to infuse at least 15 minutes. Puree the mixture with a hand blender until smooth.
Preheat oven to 300 degrees F.
In a large bowl, whisk the egg yolks with the granulated sugar. Whisking constantly, gradually pour in the hot cream mixture. Strain the mixture into a pitcher. Sprinkle the remaining corn kernels into 8 (6 to 8 ounce) ovenproof ramekins. Pour the cream/corn mixture into the bowls and arrange in a hot water bath. Bake at 300 degrees F, in the center of the oven until almost set but still a bit soft in the center, 30 to 40 minutes. The custard should "shimmy" a bit when you shake the pan; it will firm up more as it cools. Remove from the water bath and let cool 15 minutes. Tightly cover each bowl with plastic wrap, making sure the plastic does not touch the surface of the custard. Refrigerate at least 2 hours. (Or refrigerate until ready to serve, up to 24 hours.)
Preheat a broiler to very hot (or fire up your kitchen torch). Uncover the chilled custards. Pour as much sugar as will fit onto the top of one of the custards. Pour off the excess sugar onto the next custard. Repeat until all the custards are coated. Discard any remaining sugar. Place the bowls on a baking sheet or in a roasting pan and broil until the sugar is melted and well browned, 1 to 2 minutes. Or brown them with a blowtorch. Let cool 1 minute before serving.
