01 - Preheat oven to 340°F and line a baking sheet with parchment paper. Spread the cooked, dried quinoa evenly across the sheet. Bake for 15 minutes, stirring once halfway through, until completely dry and crisp. Allow to cool thoroughly before proceeding.
02 - Place chopped dark chocolate in a heatproof bowl set over a pot of simmering water, ensuring the bowl doesn't touch the water. Stir frequently until smooth and fully melted. Alternatively, microwave in 30-second intervals, stirring between each burst.
03 - Add the cooled, toasted quinoa to the melted chocolate. Fold gently until every grain is thoroughly coated. Sprinkle in sea salt and mix to distribute evenly. If using optional nuts or coconut, incorporate them now.
04 - Drop heaping teaspoons of the chocolate-quinoa mixture onto a parchment-lined tray. Use the back of a spoon to shape into small rounds approximately 1.5 inches in diameter. Space slightly apart to prevent sticking.
05 - Transfer the tray to the refrigerator and chill for 30 minutes, or until the crisps are completely firm and set. Test by gently pressing the center—it should hold its shape without leaving an imprint.
06 - Serve immediately once set. Store in an airtight container at room temperature for up to 1 week, or refrigerate for extended shelf life. These crisps also make excellent gifts when packaged in decorative tins or boxes.
