Shiitake Mushroom Temaki Hand Rolls

Directions

1. For the sushi rice, Combine the prepared sushi rice with the rice vinegar. Set it aside. 
2. For the mushroom mixture, heat the oil in a large rondeau over high heat. Add the onions and sauté until translucent, 2 to 3 minutes.
3. Add the mushrooms and sauté until they start to soften. About 3-4 minutes more adding water as needed to prevent sticking.
4. Add the garlic and scallion and cook until the scallions are wilted, and the garlic is cooked, 3 to 4 minutes.
5. Add the sushi sauce and maple syrup and reduce until slightly thickened, about 5 minutes. Remove the mixture from the pan and set aside to cool.
6. To assemble the temaki rolls, lay the nori sheets smooth side down on a clean surface. Place a scoop of seasoned rice on the left side of the nori. Wet your hand with water and spread the rice slightly outward toward the corner.
7. Place some of the mushroom mixture, avocado, carrot, and cucumber, diagonally on the rice. Fold the bottom left corner upwards, like a flag, over the mixture, so that it connects to the top center of the nori.
8. Take the right side of the nori and fold it over the middle of the roll, wetting the edge of the nori with some water, to seal the temaki.
9. Garnish with a sprinkle of sesame seeds.
