Bring a kettle of water to a boil. Put the cornmeal and salt in a large bowl, and whisk in 1 cup plus 2 tablespoons of the boiling water. Let rest about 10 minutes.
Stir in 1 tablespoon of the peanut oil. The mixture should be just pourable, but thick enough that you’ll need to use a spoon or spatula to help spread it out once it’s in the pan. If it seems too thick, add another tablespoon or two of hot water.
Put the remaining 2 tablespoons oil in an 8- to 12-inch skillet over medium heat. When it’s hot, spoon in about half of the cornmeal mixture, and, using a spatula or the back of a spoon, spread it into a round about 6 inches in diameter. Cook until the hoecake is golden around the edges and looks set throughout, about 10 minutes, then begin to loosen the edges with a spatula. When you’ve fully released the hoecake from the pan, gently flip it. Cook another 8 to 10 minutes, then transfer to a plate. Repeat with the remaining cornmeal mixture. Serve warm.
