This sushi mat (or "makisu") consists of small bamboo sticks held together with string, and is the perfect tool for making maki sushi rolls at home (see additional pictures below). 9.5" across and and 12" long. Product of China.
Make the sushi rice in a rice cooker, then when the rice is still warm gently fold 1 tablespoon of sushinoko with 300 grams steamed rice, this will make the rice "vinegared". Set aside. For a slightly different vinegar flavor, you can substitute 2 tablespoons sushizu for the sushinoko.
