01 - Wash the oranges thoroughly under running water. Using a sharp knife, slice off the top and bottom of each orange, then score the skin into quarters. Carefully peel away the skin, keeping a thin layer of white pith attached for texture.
02 - Slice the peeled orange skins into uniform strips approximately ¼ inch wide for even candying.
03 - Place the orange strips in a saucepan, cover with cold water, and bring to a rolling boil. Drain completely, then repeat this blanching process two more times to remove excess bitterness from the pith.
04 - In a clean saucepan, combine the sugar and water. Stir over medium heat until the sugar has fully dissolved and the mixture is clear.
05 - Add the blanched orange peels to the syrup and simmer uncovered for 45 to 60 minutes, stirring occasionally, until the peels appear translucent and feel tender to the touch.
06 - Using tongs or a fork, transfer the candied peels to a wire rack set over a sheet of parchment paper. Allow them to dry at room temperature for at least 2 hours, or preferably overnight, until the surface is no longer tacky.
07 - Place the chopped dark chocolate in a heatproof bowl set over a pot of barely simmering water, ensuring the bowl does not touch the water. Stir gently and occasionally until completely smooth and glossy.
08 - Dip each candied orange peel strip halfway into the melted chocolate, allowing the excess to drip back into the bowl. Arrange each piece on a parchment-lined tray with space between them.
09 - Let the chocolate set completely at room temperature, or refrigerate the tray for 15 to 20 minutes to speed up the process. Once firm, transfer the finished peels to an airtight container and store in a cool, dry place for up to 2 weeks.
