KALE AND POTATO PURéE

Steps:

• Cook the kale in a pot of boiling salted water (1 1/2 tablespoons salt for 4 quarts water), uncovered, until tender, about 7 minutes. Drain, then immediately transfer the kale to an ice bath to stop the cooking. When kale is cool, drain but do not squeeze.
• While kale cooks, peel the potatoes and cut into 1/2-inch pieces. Simmer in the cream, salt, and pepper in a heavy medium saucepan, covered, stirring occasionally, until tender, 15 to 20 minutes.
• Purée the potato mixture with the kale in 2 batches in a food processor until just smooth (use caution when blending hot liquids). Transfer to a 4- to 5-quart heavy saucepan and cook over low heat, stirring frequently, until heated through. Season with salt and pepper.
• DO AHEAD
• The PURÉE can be made 1 day ahead and chilled. Reheat over low heat, stirring frequently.
