Combine creamed mixture, dry mixture, and lemon zest. Incorporate ingredients just until the dough holds together without over working the dough. If the dough is too dry add ice water one teaspoon at a time until the dough holds together. Chill dough while stuffing the pears. In a small bowl combine hazelnuts, brown sugar, flour, melted butter, salt cherries and zest.
Stuff pears into mixture.
Cut into 4 squares. Drape each square over a pear. Poke a small hole in the center of each square and fit the stem through the hole. Wrap dough around the pears, cutting off any extra dough. Press out all the seams.
