Hint
Use spring leek leaves instead of nori to make your sushi. They cook very quickly because the fibers are very thin and tender.

1. Cut off the tops of the leaves and rinse the leeks quickly under cold water.
2. Separate each leek leaf. Blanch for 3 minutes in boiling water.
3. Drain the leaves and spread out on a work surface. Roll each prawn in a leek leaf and fasten with a small wooden pick.
4. Steam the rolls in a bamboo steamer for 8 minutes or microwave for 2 minutes. Serve with soy sauce.
