01 - Wash oranges thoroughly under running water. Using a sharp knife, slice off the top and bottom of each orange, then score the skin into quarters and carefully peel away the rind, keeping a thin layer of white pith intact.
02 - Slice the peels into uniform strips approximately ¼ inch wide for even candying.
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 sugar and water. Stir over medium heat until the sugar fully dissolves, then add the blanched orange peels.
05 - Simmer the peels in the syrup uncovered for 45 to 60 minutes, stirring occasionally, until the strips turn translucent and feel tender throughout.
06 - Using tongs or a fork, transfer the peels to a wire rack set over a sheet of parchment paper. Allow to dry at room temperature for at least 2 hours, or preferably overnight, until no longer tacky to the touch.
07 - Place chopped dark chocolate in a heatproof bowl set over a pot of barely simmering water, making sure the bowl does not touch the water. Stir occasionally until completely smooth and glossy.
08 - Dip each candied orange peel strip halfway into the melted chocolate, allowing excess to drip back into the bowl. Arrange on a parchment-lined tray.
09 - Let the chocolate set completely at room temperature, or refrigerate the tray for 15 to 20 minutes to speed up setting. Once firm, transfer to an airtight container and store in a cool, dry place for up to 2 weeks.
