What Is Sushi? Exploration of Japanese Rice

 SushiMost people in the US know of sushi. They have most likely tried it before and it has become synonymous with Japanese food. But what is sushi? In classical Japanese, it means "sour." It is said that when somebody first ate sushi rice, they exclaimed "Sushi!" translating to "It's sour!" So what's truly essential for sushi is the flavored rice. And rice alone seemed like a boring post so I thought I would share how to enjoy temaki sushi (手巻き寿司) or hand rolled sushi.

Let's first start with the purchasing of rice. I am a firm believer that rice is worth spending money on. A premium 15 pound bag of rice usually costs around $30 and can last you months in a household of two. And we eat rice all the time. So many Japanese dishes rely on rice, so please, don't skimp. My favorite brand is Kagayaki Select but usually the price will tell you the quality of the rice.

Japanese RiceJapanese rice, often referred to as sushi rice in the US, is a short grain rice high in starches. The extra starch gives it the sticky quality. But you don't want it to be too sticky, you want to have just the right amount of sheen and tenderness. We'll get to how you achieve this later. Rice used for sushi is different than Japanese glutinous rice or mochigome (もち米), which is used to make mochi.

Washing RiceHere are the steps to making delicious Japanese rice:
1. Wash the rice thoroughly with cold water: Unlike other rice, you need to remove the surface starch of Japanese rice so that the cooked rice is not too sticky. I like to use a rice washing bowl which has a sieve at the top making it easier to drain the water after each washing. Fill the bowl with water to cover the rice and vigorously swish your hands in the rice water and drain. Repeat until the water is no longer cloudy. With Kagayaki it's about 3 times. Some of the cheaper rice may take longer.
2. Drain the rice completely and transfer into a pot with a heavy lid or the bowl of a rice cooker. If you're using a rice cooker, it probably has a measuring cup and will guide you on how much water to add. If you're using a pot, it's 1:1 rice to water ratio by volume with just a tad more water.
3. The third is the last step in a rice cooker. You just press cook and wait until the rice is perfectly cooked. If you're going stove top, let the rice soak for 30 minutes to an hour if you have the time. It helps to cook the rice evenly as the rice absorbs the water.
4. Cooking the rice stove top is a bit of a challenge. You have to keep the lid on the pot the entire time so you have to constantly listen to the sound of the water. Bring the water to a boil over high heat and immediately turn down to low. Cook for 10-15 minutes or until the water is completely absorbed and then let it steam off the heat for another 10 minutes.
5. Open the lid (finally!) and mix the rice carefully so as not to crush the grains.

Sushi Rice
When making sushi rice, you flavor the rice once it's fully cooked. Because we add liquid once again, I usually cook the rice with slightly less water. If you're lazy like me and make a lot of sushi, you can use the Mizkan Sushi Rice Vinegar and follow the steps to flavoring the rice. Otherwise, all you need is rice vinegar, salt, and sugar. See below for the full sushi rice recipe.

Sushi Rice Finished
You can use this sushi rice for chirashi, nigiri, inari, maki, gomoku, oshi or temaki. One day I will get to all of these, but today we'll talk temaki. The idea is that everyone shares a platter of sashimi grade fish (or veggies if you're vegetarian) and assemble individual rolls in your hand.

Sashimi
Make sure to get your fish from a trusted fishmonger. If you're in NYC, you can go to a Japanese grocery store like Sunrise Mart or the Union Square Greenmarket. This time I got my fish in my hometown Boston, so I went to Sakanaya which specializes in sashimi grade fish.

Temaki Sushi
I usually take a quarter sheet of seaweed in my left hand and lay out some sushi rice on top and layer with my favorite cut of sashimi and maybe some wasabi or julienned cucumbers. I roll up the seaweed and bite right in. The best part is that it's so communal as everybody shares everything!

Prep time: 
Cook time: 
Total time: 
Ingredients
  • 1.5 cup dry Japanese rice
  • 1.5 cup water (or slightly less)
  • 3 tbsp rice vinegar
  • 1 tbsp sugar
  • 1 tsp salt
Instructions
  1. Make the rice either on stove top or in a rice cooker (see above post for instructions on washing and cooking Japanese rice)
  2. Heat the rice vinegar, sugar, and salt in a small pot until the sugar and salt are completely dissolved and let the mixture cool
  3. Once the rice is cooked, immediately transfer to a large clear bowl
  4. Pour the vinegar mixture over a rice spatula over the bowl as you move the spatula in a circular motion (the idea here is that you want the vinegar to spread evenly)
  5. Fold the seasoning into the rice so that each grain is coated with the mixture. Be careful not to smash the grains and work near a fan or have someone manually fan for you to evaporate some of the bite out of the vinegar and cool down the rice rapidly In order to preserve the sheen, you want to work as quickly as possible
