Combine cherries and orange juice/extract in small bowl and microwave until hot, about 30 seconds; let sit until cherries have softened and mixture is cool, about 15 minutes (just let them sit while you prepare the other ingredients).
Reserve 1 cup ladyfingers. Process remaining ladyfinger in food processor to fine crumbs, about 30 seconds. This will yield about 3/4 cup.
Place cream and chocolate in a medium, microwave-safe bowl, heat on 50 percent power, stirring frequently, until melted and smooth, about 60 seconds total. Add salt and ladyfinger crumbs and stir to combine. Add pistachios, reserved ladyfingers, and cherry mixture (including juice). Stir until thick dough forms.
Divide dough in half and place each half on a large sheet of plastic wrap (about 12' long). Use plastic to roll each dough into tight 6-inch log, twisting ends well to secure. Refrigerate dough logs until firm, at least 3 hours. Chilled dough can be stored in refrigerator for up to 3 days.
When ready to serve, place confectioners' sugar in shallow dish. Unwrap dough logs and roll in sugar until well coated, brushing off excess. Cut each log into 1/2-inch slices. Serve.
