01 - Wash oranges thoroughly. Cut off the top and bottom of each orange, score the skin into quarters, and carefully remove the peel along with a small portion of the white pith.
02 - Slice the peels into uniform thin strips, approximately 1/4 inch wide.
03 - Place the strips in a saucepan, cover with cold water, and bring to a boil. Drain completely, then repeat this blanching process two more times to draw out excess bitterness.
04 - In a clean saucepan, combine the sugar and water. Stir over medium heat until the sugar has fully dissolved.
05 - Add the blanched orange peels to the syrup. Simmer uncovered for 45 to 60 minutes, stirring occasionally, until the peels appear translucent and feel tender throughout.
06 - Using tongs or a fork, transfer the peels to a wire rack set over a sheet of parchment. Allow them to dry at room temperature for at least 2 hours until no longer sticky; overnight drying yields the best results.
07 - Set a heatproof bowl over a pot of barely simmering water, ensuring the bowl does not touch the water. Add the chopped dark chocolate and stir occasionally until completely smooth and glossy.
08 - Dip each candied peel strip halfway into the melted chocolate, allowing any excess to drip back into the bowl. Arrange the dipped peels on a parchment-lined tray.
09 - Let the chocolate coating set completely at room temperature, or refrigerate the tray for faster results. Once firm, transfer the peels to an airtight container and store in a cool, dry place for up to 2 weeks.
