Preparation:

To make the purée: Combine the strawberries and sugar in a food processor or blender and purée. Strain through a fine-meshed sieve and set aside.

To make the coating: Melt the butter in a medium sauté pan and stir in the breadcrumbs and sugar. Sauté until golden and crispy. Set aside in a shallow bowl or plate.

To make the dumplings: In a large bowl, mix the bread cubes, cheese and zests. Split the vanilla bean and scrape the tiny seeds into the mixture; discard the pod (or place in granulated sugar to make vanilla sugar). With a wooden spoon, stir in the egg, pinch of salt and sugar. Let stand for 5 minutes.

Bring a large pot of water to a boil and add 1/2 cup rum. Form the dumpling mixture into 2-inch balls. Drop the dumplings into the boiling water and cook 5 minutes. Remove with a slotted spoon and drain on towels.

To serve: Melt the chocolate in the top of a double boiler over barely simmering water. Put into a pastry bag fitted with a very small plain tip, or put into a small plastic bag and snip a tiny hole in one corner. Pipe a design on each of four dessert plates, incorporating two large circles in the design. Let set for 1 minute. With the tip of a spoon, fill the circles with strawberry purée. Roll the dumplings in the coating mixture and place two or three dumplings on each plate. Garnish each plate with a few blueberries, one split strawberry and a few raspberries, topped with a mint leaf. Dust the dumplings with confectioners' sugar.
