Gently brush the nori sheets with vegetable oil using a soft pastry brush.

Heat a large skillet or non-stick pan over medium-low heat.

Place a sheet of nori in the hot pan for a few seconds until it becomes crisp and dark green.

Quickly flip the sheet over with chopsticks or tongs and toast the other side for a few seconds.

Remove the toasted nori sheet and place it on a large cutting board.

While the nori sheet is still warm, lightly sprinkle each side with unrefined sugar.

Repeat the oiling, toasting, and sugaring process with each remaining nori sheet.

Stack all the sugared and toasted nori sheets in one pile.

Cut the pile of sheets in half lengthwise.

Cut the lengthwise halves crosswise to make 6 rectangular pieces of nori from each sheet.

Stack the smaller nori sheets in a pile and place a toothpick in the center to hold them in place.
