01 - Line a baking sheet with parchment paper or a silicone mat.
02 - Place the chocolate and coconut oil (if using) in a heatproof bowl and melt gently over a double boiler or in 20-second bursts in the microwave, stirring until smooth.
03 - Add the raisins to the melted chocolate and stir until all are thoroughly coated.
04 - Using a fork or slotted spoon, lift the raisins out allowing excess chocolate to drip off, then spread in a single layer on the prepared baking sheet.
05 - If raisins clump together, separate them with a fork for individual pieces, or leave clusters intact if desired.
06 - Refrigerate for 30 to 45 minutes until the chocolate sets completely.
07 - Break apart any clusters as preferred and store in an airtight container at room temperature or in the refrigerator.
