Making sushi rice is an art in itself. If you're short on time, you can use an electric rice cooker, but I've found the following method works well:
- Rinse & drain the rice 10 times. This is a bit time-consuming, but you want to rinse the rice until you can see individual grains through the water. I've found that 10 times is a reliable number.
- In a large pot, place the drained rice and 1 cup of filtered water, kombu, and potato starch. Cover and bring to a boil.
- Lower the temperature to medium and simmer for 10-15 minutes.
- Turn off heat and let the rice continue to cook for another 10 minutes.
- While the rice is cooking, prepare the rice seasoning. Mix the vinegar, sugar, and salt thoroughly.
- Once the rice is fully cooked, transfer it to a hangiri, a Japanese wooden bowl, or any container that has a decent amount of flat surface area to lay out the rice.
- Sprinkle the rice seasoning on the rice while cutting and folding the rice with a rice paddle. Work the rice quickly to cool and coat the rice with even seasoning.
- When you are done, the rice should have a glossy appearance.
- Cover the rice with a towel or transfer to an insulating container to keep it warm and moist.
To assemble the rolls with the sushi rice on the outside of the nori sheets:
- Place the nori in landscape mode.
- Apply a layer of sushi rice approximately 2-3 rice kernels thick. Leaving about a 1/2 inch gap at the bottom. The gap is where the nori will adhere to itself (with a few of rice kernels) without doubling up on rice layers.
- Wipe the cutting board to keep it damp and flip the nori, like you would a book, such that the rice is now on the cutting board.
- Fill the sushi with the prawn, asparagus, scallions and cucumber.
- Roll the sushi and adhere the nori to itself with a few rice kernels. At first, the rolls will not be pretty. Don't worry; the sushi mat will fix that.
- With one half of an avocado, peel it and slice it thinly width-wise. Spread the slices evenly to be exactly the length of the sushi roll.
- Place the avocado slices on top of the sushi roll.
- With a sushi rolling mat, wrapped in plastic wrap, place the flat side (not the bumpy, round side) down on the sushi. Form the sushi into a square roll.
- Cut the roll into 8 equal sized pieces.
- Place the cut sushi on a serving platter. Squeeze dots of mayonnaise on top and place a slice of serrano pepper on top of the mayonnaise.
- Enjoy immediately! :)
