  1. 3 ears of corn, kernels cut off and cobs cut into 2-inch lengths
  2. 1 1/2 cups heavy cream
  3. 2 pounds Yukon Gold potatoes, peeled and cut into 2-inch chunks
  4. 2 garlic cloves, smashed
  5. Salt
  6. 3 tablespoons unsalted butter
  7. 1/4 cup sour cream
  8. Freshly ground pepper
  1. In a medium saucepan, bring the corn cobs and cream to a simmer. Remove from the heat, cover and let steep for 30 minutes; discard the corn cobs.
  2. Meanwhile, in a large saucepan, cover the potatoes with water. Add the garlic and a large pinch of salt. Bring to a boil; cook over moderately high heat until the potatoes are tender, 20 minutes.
  3. Meanwhile, melt 1 tablespoon of the butter in a medium skillet. Add the corn kernels and 2 tablespoons of water, cover and cook over moderate heat until tender, about 5 minutes. Uncover and cook the corn over moderate heat, without stirring, until browned on the bottom, about 4 minutes. Scrape the corn into a blender. Add the corn-infused cream and puree until smooth.
  4. Drain the potatoes and garlic and return to the saucepan. Shake the potatoes over moderately high heat for 1 minute to dry them; remove from the heat and mash with a potato masher. Stir in the corn cream, sour cream and the remaining 2 tablespoons of butter. Season with salt and pepper and serve.
