Peel both oranges and separate them into clean segments. Remove any white pith that remains.

Place the chopped dark chocolate in a microwave-safe bowl. Heat in 20-second bursts, stirring between each, until fully melted and smooth.

Line a baking sheet with parchment paper. Dip each orange segment halfway into the melted chocolate and let excess drip off.

Place the dipped segments on the prepared sheet. While the chocolate is still wet, sprinkle each piece lightly with smoked sea salt and red chili flakes.

Let the chocolate set at room temperature for 20 minutes before serving.
