1 medium seedless orange (thin-skinned)
1 cup raisins
1 cup pitted dates
1 cup pitted prunes
1 cup dried apricots
Cut orange into chunks, but do not peel. Cut away both the navel and the stem end. In the processor, process orange until finely ground, about 20 seconds. Add remaining ingredients and process until finely ground, about 15 to 20 seconds. Scrape down sides of bowl as necessary.
Note: 1 cup filling is enough to fill 12 to 16 Hamentashen, depending on size. Mixture can be prepared in advance and refrigerated for several days, or frozen.
