Combine granulated sugar and water in a large saucepan. Place over medium heat, stirring until sugar fully dissolves and the mixture starts to boil.

Lower heat to maintain a gentle simmer. Arrange orange slices in a single layer in the syrup. Simmer for 45–60 minutes, occasionally turning slices, until rinds become translucent.

Optionally, coat dried slices in granulated sugar for a frosted appearance or dip halves in melted chocolate with a pinch of flaky salt. Store in an airtight container between layers of parchment paper at room temperature for up to 1 month.
