Dry 1 sheet roasted seaweed for sushi (nori) either in a dry frying pan over a low heat (no oil), or pass it back and forth over an open flame (like a gas burner) until crisp. Be careful not to let it brown or burn.
Fold it in half, and tear or cut along the seam. Cut each piece in half, then half again until you have 8 small rectangles.
Stack 2-4 rectangles, then use sharp kitchen scissors to cut about 2mm thin strips.
Alternatively, cut them with a long, sharp knife. (This method is more prone to tearing and uneven cuts, depending on your knife and skills.)
Store in an airtight container or zip bag with a silica gel packet. Use as a topping on your favorite Japanese recipes, enjoy!
Notes
When re-crisping the nori: keep it moving so it doesn't burn. This applies to both the open fire, where you need to gently fan it over the flame, and in the dry pan, flip every 10 seconds. It's done when the texture is crisp enough to split when folded, and has a toasty sea-air aroma.Avoid stacking more than 4 at a time: stacking too many will result in uneven cuts.Make sure your cutting utensil is sharp. Ideally, sharpen it right before you start.Kizami nori can be used as a topping for many dishes. It is often sprinkled over things like chirashizushi, zaru udon,zaru soba, and donburi. It also makes a great addition to salads, I even sprinkle it over my teriyaki pizza!
