How to Make It
In a large, deep skillet, heat the olive oil. Add the garlic and cook over high heat, stirring, just until browned in spots, about 1 minute. Add the kale by the handful and cook, stirring, until wilted and any liquid has evaporated, about 5 minutes. Season the kale with salt and pepper, transfer to a cutting board and coarsely chop.
In a large saucepan, combine the milk, water, butter and 2 teaspoons of salt and bring to a boil. Whisk in the polenta in a thin stream and cook over moderate heat, whisking constantly, just until it begins to thicken, about 3 minutes. Add the wilted kale and cook over low heat, stirring frequently with a wooden spoon, until the polenta is very thick and no longer gritty, about 20 minutes. Stir in the Creamy Ricotta, season with salt and pepper and cook just until the ricotta is heated through, about 3 minutes. Transfer the polenta to a bowl and serve right away.
