Make these sweet and savory bites for easy and tasty entertaining. Both the blueberry chutney and muffins can be prepared ahead of time then assembled just before serving. Round out a meal by making a double batch of chutney and serve with baked ham.
Bring blueberries, brown sugar, onion, ginger, lemon juice and zest, chile, mustard, cinnamon and salt to a simmer in a nonreactive small saucepan over medium heat, stirring often. Reduce heat to medium-low and simmer, stirring often, until juices are syrupy, about 15 minutes. Transfer to a bowl and let cool completely.
The chutney can be cooled, covered, and refrigerated up to 5 days ahead. Bring to room temperature before serving.
Preheat oven to 400°F. Lightly butter 24 mini-muffin cups.
Sift cornmeal, flour, sugar, baking soda and salt together in a medium bowl. Whisk together buttermilk, melted butter, and egg in a small bowl. Pour buttermilk mixture into cornmeal mixture and whisk just until smooth; do not overmix. Divide the batter equally among the muffin cups.
Bake until muffins are golden brown and spring back when pressed on top with a finger, about 15 minutes. Let cool 5 minutes. Remove from pans. Enjoy warm or let cool to room temperature.
Split each mini-muffin crosswise in half. For each, dollop about 1 teaspoon chutney to bottom half, top with a piece of prosciutto, folded to fit, and replace the muffin's top half. Serve warm or at room temperature.
