Cut each pear in half and remove the core. Cut each half into 5 or 6 thin wedges. Divide the filling evenly over the tarts, leaving a small border around the edges. Arrange the pears in a circular pattern on the filling. Sprinkle the sugar over the pears. Bake until the pears are lightly caramelized, about 20 minutes.

In an electric mixer fitted with a paddle, combine the butter and sugar until light and fluffy. Add the egg and the zest. Add the flour-nut mixture and mix to combine.
