💡 Tip: Always rinse your short-grain Japanese rice under cold water until the water runs nearly clear — this removes excess surface starch and prevents the rice from becoming gummy. Typically 3-5 rinses are needed. Let the rinsed rice drain for 30 minutes before cooking for best texture.
💡 Tip: Season the rice while it is still hot and freshly cooked. Use a wooden or plastic rice paddle (shamoji) and fold the vinegar mixture in gently with a slicing motion — never stir or mash. Fan the rice as you fold to cool it quickly and give it a glossy finish.

Sushi rice is the base of every real sushi. The word “sushi” in Japanese actually means “sour taste” because you season it with vinegar. You can say also “rice with vinegar” or “sour rice” Every food with that rice is called sushi, even if it does not have fish.

Sashimi is simply raw meat cut specially.

How to Make Sushi Rice

In Japan you expect good fish, but the best sushi restaurants stand out by the quality of their rice. Good sushi rice sits between soft and firm. The grains stay separate without being gluey.

Making rice is among the most honored skills in sushi. Students in Japan work under a master for about five years before they can cook the rices thmeselves. The recipe of the sushi chef usually stays a trade secret.

For sushi you use only short-grain rice. Long-grain or processed kinds simply do not work. Cooked sushi rice shines, sticks and is chewy.

Popular types are Sasanishiki and Koshihikari, that you mix from old and new harvests for the best quality. CalRose, medium-grain Japanese rice from California, works also well.

The main difference of sushi rice to regular rice is the after-cooking. You add sweet vinegar to give taste, gloss and stickiness. For the vinegar mix you heat it in a pan with sesame oil and seaweed until salt and sugar dissolve.

After cooking you put the rice in a wide tin. With a wooden or plastic spoon you spread them. Vinegar you pour on and mix carefully.

It cools for 20 to 30 minutes, while you let steam exit every minute.

Cold rice is a Mistake. It loses sweetness, simplicity goes and it changes the taste of other parts. During dip in soy sauce, only the edge of the fish touch it.

Soy sauce on rice could destroy the whole sushi. Occasionally you leave it without any sauce.

One cup regular sushi rice gives around three rolls. Every roll becomes six to eight bits. Two rolls for one person are usual.

Two cups regular rice make eight rolls, so four servings. Leftover rice you can reheat, but it does not taste like fresh. You use it for ricebowls or risotto-like foods.
