01 - Preheat oven to 325°F. Line a baking sheet with parchment paper.
02 - In a mixing bowl, combine cooked rice, salt, and rice vinegar. Stir thoroughly until salt dissolves.
03 - Add toasted sesame oil, white and black sesame seeds, and shredded nori to the rice mixture. Mix until evenly distributed.
04 - Scoop heaping teaspoons of the mixture onto the prepared baking sheet. Flatten each into disks roughly 1/8-inch thick using a wet spoon or fingertips.
05 - Lightly brush or spray the tops with neutral oil to promote even browning.
06 - Bake for 25 to 35 minutes, flipping crisps halfway through, until lightly golden and crisp.
07 - Transfer crisps to a rack and allow to cool completely before enjoying or storing in an airtight container.
