Once the rice cools, place half a nori sheet with its shiny side down on the sushi mat.
4 nori sheets
Spread the rice evenly on the nori, leaving an inch (2.5cm) at the top. Be sure to fill in the left and right sides completely. The more traditional way is to use your hands to do this but I prefer just using (rice) spoon.
Fold three shiso leaves, each into half lengthwise, then place them about an inch (2.5cm) from the bottom. Then take out the pit of your umeboshi plum. Tear out each plum into 4-5 parts, then spread them on top of your shiso leaves in a horizontal line. One sushi roll should use 3 shiso leaves and 1 to 1.5 plums.Be careful not to put too much umeboshi since they have a strong taste and can overpower the recipe that way. Remember that it's better to have too few than too many umeboshi! 24 shiso leaves, 35 grams umeboshi
(Optional) If you are using avocado, add it on top of the umeboshi. Also sprinkle your sesame seeds over the sushi rice now, if using.
1 medium avocado, 2 Tablespoons white sesame seeds
Roll the sushi tightly using the sushi mat, applying gentle pressure by pressing the sushi roll (and sushi mat) to keep it secure. If needed, seal the roll by brushing the top edge of the nori using a damp finger (wet, but not dripping with water).
Repeat the process with the remaining nori sheets, sushi rice, and vegetables.
Then slice them into bite-sized pieces, about 8 pieces per roll. It's easiest to first slice the roll into two halves, then continue slicing each piece into two (see process shots above in the post).
Serve the Umeboshi Sushi on its own, with vegan mayo, or soy sauce for dipping!
