There is not much on measurements as it is all to taste.
Roasted nori, cut into 4 inch squares
Furikaki
Sushi rice, cooked
Rice vinegar
Asparagus, trimmed
Kewpie mayonnaise (American brand mayo is okay to use, but Kewpie, by far, is a better choice.)
Pork floss / pork sung (optional)
Instructions
After cooking rice, allow to cool slightly. Mix in a few glugs of rice vinegar and a few sprinkles of furikake.
Meanwhile, bring pot of water to boil and prepare a bowl of ice water nearby. Add asparagus to boiling water, and cook for 30 seconds to bring out the brilliant green color, then immediately transfer to the bowl of ice water to stop the cooking. Drain well and blot dry. Cut the asparagus spears into around 6-inch lengths. Set aside.
Set up an assembly line with the components.
Take a couple spoonfuls of rice, mold them gently into an oval and place in the middle of a cut piece of nori.
Mix a bit of mayo in with the asparagus and add 2 to 3 spears on top of the rice. Sprinkle with furikake, add another squirt of mayo, and close opposite edges of nori. If you want a little crunch ans salt and eat meat, a sprinkle of pork floss (pork sung) is a great addition.
Serve immediately. Assembled, these should be eaten the day they are made.
