01 - Wash the oranges thoroughly under running water. Using a sharp knife, slice off the top and bottom of each orange to create a stable base. Score the peel into four vertical sections and carefully remove each section, keeping a thin layer of white pith attached for texture.
02 - Slice the removed peel sections into uniform strips approximately ¼ inch wide for even candying and a polished final appearance.
03 - Place the strips in a saucepan and cover with cold water. Bring to a rolling boil, then drain completely. Repeat this blanching process two additional times to draw out excess bitterness from the pith.
04 - In a clean saucepan, combine the sugar and water. Stir continuously over medium heat until the sugar has fully dissolved and the mixture is clear.
05 - Add the blanched orange peels to the syrup. Simmer uncovered over low heat for 45 to 60 minutes, stirring occasionally, until the peels turn translucent and feel tender to the touch.
06 - Using tongs or a fork, transfer the candied strips to a wire rack set over a sheet of parchment paper. Allow them to air-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 the chocolate is completely smooth and glossy.
08 - Dip each candied orange strip halfway into the melted chocolate, allowing any excess to drip back into the bowl. Place each coated piece onto a parchment-lined tray, leaving space between strips to prevent sticking.
09 - Allow the chocolate to harden fully at room temperature, or refrigerate the tray for 15 to 20 minutes to speed up the process.
10 - Transfer the fully set chocolate-covered orange peels to an airtight container. Store in a cool, dry place for up to 2 weeks.
