Wash rice at least 3 times or until water is clear. Fill rice cooker or casserole with water to about 1-inch over rice. I highly recommend a rice cooker B more than 2 billion people use them in Asia for a reason. Slowly heat vinegar, mirin and sugar until very hot but not boiling. Fold in >su= (vinegar and sugar) with the hot rice, add enough so that the rice has a tart/sweet taste. Rice should be shiny, not mushy. Carefully put rice in a clean bowl, cover with a damp cloth and let rest for 30 minutes. Lay down nori on sushi mat and lightly pat on rice on bottom 2/3rds of nori. Place smoked salmon, jicama, daikon, gari and a touch of wasabi oil. Roll, moisten end and let rest.
