Wash the oranges thoroughly and slice into thin, even rounds
In a wide-bottomed saucepan, combine the water, sugar, and vanilla. Stir over medium heat until the sugar has fully dissolved
Add the orange slices to the saucepan in a single, even layer and ensure they're fully submerged in the syrup
Bring to a gentle simmer, cover the pot, and cook for 30–40 minutes until the slices look translucent
Using tongs, carefully transfer each slice to a cooling rack set over a parchment-lined baking sheet to catch drips
Let them dry and firm up overnight in the turned-off oven with the door open, or chill in the fridge for 20 minutes then the freezer for 10 minutes
Chop the chocolate bars and add them to a small saucepan with 1–2 tbsp coconut oil. Warm over low heat, stirring until smooth and glossy
Line a baking sheet with parchment and dip each candied orange slice into the melted chocolate, then lay flat on the parchment
Before the chocolate sets, sprinkle with flaky salt and transfer to the fridge for 10–15 minutes to harden
Store in an airtight container in the fridge for up to a few weeks
