Ingredients 7 ½ ounces blueberries (1 ½ cups) 6 ounces raspberries or blackberries (1 ½ cups) 12 strawberries, hulled, and halved or quartered if large (1 ½ cups) ½ cup plus 2 tablespoons packed light-brown sugar ¼ cup plus 1 tablespoon water ½ vanilla bean, split and scraped, pod reserved Salt 1 tablespoon cornstarch ½ cup all-purpose flour ½ teaspoon baking soda ⅛ teaspoon freshly grated nutmeg 2 tablespoons cold unsalted butter, cut into small pieces ¼ cup buttermilk Directions Bring berries, 1/2 cup sugar, 1/4 cup water, the vanilla seeds and pod, and a pinch of salt to a simmer in a saucepan over medium heat. Cook, covered, for 5 minutes. Whisk together cornstarch and remaining tablespoon water; add to berries. Simmer for 1 minute. Let stand while making dough. Mix together remaining 2 tablespoons sugar, the flour, baking soda, grated nutmeg, and 1/8 teaspoon salt. Rub in butter using your fingers until very small pieces remain. Stir in buttermilk until dough forms. Return berry mixture to a gentle simmer over low heat, and add 6 mounds of dough. Cook dumplings, covered, until cooked through, about 10 minutes. Remove pod. Serve warm. Cook's Notes Serving idea: Top slump with ice cream. Rate it Print
