|leftover salmon wrapped in sushi rice|
Placed 1/2 of the rice on a nori sheet, topped it with a line of salmon and a little horseradish-mayonnaise (2 tablespoons mayonnaise, 1 tablespoon grated horseradish) on top of the fish and rolled it up.
For the second roll I placed the rice on a cling film sheet, followed by a line of salmon with mayonnaise topping and covered it with a nori sheet and rolled it up. Afterwards I rolled it in white sesame.
My knife did not do the job very well. Has to be sharpened - tomorrow someone has something to do about it.
*) this is not what you get when ordering sushi but it looks alike - I have no better name.
