How to Make Shiitake Nigiri
Whisk Together: In a small non-metal bowl, quickly whisk the rice vinegar, sugar, and sea salt until they dissolve, which should take around 2 minutes. Cover tightly and refrigerate if not using right away.
Rinse the Rice: Place the short-grain rice in a medium bowl, cover it with cool water, and swish it around before draining. Repeat this process three times for thoroughly rinsed rice.
Let it Drain: Rinse the rice under cool water until it runs clear, then let it sit for 10 minutes to allow excess water to drain off.
Cook the Rice: Transfer the cleaned rice into a rice cooker and add the specified amount of water. Cook for 40 minutes without lifting the lid for best results.
Slice the Rice: Once cooked, transfer the rice to a large, flat cutting board. Using a soaked wooden paddle, gently cut the rice into pie slices to release steam.
Dress the Rice: Drizzle 1/4 cup of the prepared sushi rice dressing over the rice, tossing gently to combine. Repeat two more times until you ve added a total of 3/4 cup of dressing.
Cool Down: Spread the rice into a thin layer and allow it to cool for 10 minutes. Then, flip the rice to cool for an additional 5 minutes.
Cover and Store: Transfer the sushi rice to a non-metal bowl or container; cover it with a damp cloth to keep it moist until ready to use, within 4 hours.
Prepare Furikake: Cut the nori sheet into thin strips, place in a food processor, and add sesame seeds, golden flax seeds, salt, and sugar. Pulse until everything is nicely combined.
Preheat the Oven: Set your oven to 350ËF (175ËC) and line a baking sheet with parchment paper.
Mix the Sauce: In a small bowl, combine soy sauce and tomato paste. Spread this mixture evenly on the lined baking sheet in a thin layer. Bake for 15 minutes and allow it to cool.
Make Furikake Mix: Break the cooked tomato paste into small pieces and mix them into your prepared furikake mixture.
Saut Mushrooms: Drizzle a little oil into a large skillet over medium heat. Score the tops of the shiitake mushrooms, then add them to the heated pan and cook until fragrant, about 2 minutes. Remove from the skillet afterward.
Slice Nori for Wrapping: Cut the remaining nori sheet crosswise into 8 equal strips, laying the foundation for your nigiri.
Form the Rice Beds: Wet your hands and take walnut-sized pieces of rice, rolling them into rectangular shapes. Repeat until you have 8 beds of rice.
Assemble the Nigiri: Place one mushroom, scored side up, atop each shaped rice bed. Wrap a piece of nori around the mushroom and rice to secure everything.
Garnish and Serve: Arrange the nigiri on a platter and top each piece with your homemade tomato furikake, finely grated ginger, and sliced green onion. Serve immediately and enjoy!
Optional: Serve with extra soy sauce on the side for dipping.
