Prep the cherries: Drain well and pat the cherries completely dry; let them sit briefly so excess moisture can evaporate.
Make the fondant center: Mix powdered sugar, corn syrup, cherry juice, and water into a thick, moldable fondant. Adjust with tiny splashes of liquid if needed.
Wrap the cherries: Flatten a small piece of fondant, wrap it around a cherry, seal completely, and lightly dust with powdered sugar. Place on a lined tray.
Chill the centers: Refrigerate or freeze the cherry-fondant balls for 1–2 hours so they firm up for dipping.
Melt the chocolate: Warm chocolate gently (microwave or double boiler) with optional oil/butter, stirring until smooth and glossy.
Dip the cherries: Using a fork, dip each chilled ball into melted chocolate, let excess drip off, then place on parchment. Patch any small cracks with extra chocolate.
Set and enjoy: Let the chocolate harden fully at room temp or in the fridge.
Optional—but highly recommended: Let them rest for several days to 1–2 weeks to allow the fondant to liquefy into that classic cherry cordial center.
