The Further FAQ - Detailed Information About Sushi And Sashimi
Beyond The Basics: Making Sushi at Home, And Where To Find The Best Fish
Over the years, many questions have been asked in the alt.food.sushi Usenet group, which inspired this website, about sushi and related information. Here we have attempted to collect the ones that have surfaced most frequently, and waned to answer them in greater depth on the website. As Jiro Ono, one of, if not *the* best known sushi chef said, “I do the same thing over and over, improving bit by bit. There’s always a yearning to achieve more. I’ll continue to climb, trying to reach the top, but no one knows where the top is.” There is nothing cryptic about his comment, as a sushi expert, he understands that there is always more to learn, and we hope to continue adding more information as we receive questions and requests from our readers, and research answers.
Nutritional and Diet Information
Is sushi on low-carb diets?
While sushi itself is not a part of a low-carb diet or lifestyle due to the amount of carbohydrates in the rice, sashimi is perfectly fine since it is only fish without rice or nori. While almost all fish has no carbohydrates or close to none, there are a few items that contain some, such as surimi (imitation crab meat) which is usually found in California rolls.
Calories, Nutrition and Diet Information
The Sushi FAQ now has a page devoted to the nutritional and calorie content of the most popular sushi items, with new information being added on a regular basis. For detailed nutrition and calorie information on sushi, sashimi, and maki (rolls) please visit our page on the nutritional and calorie content for various common sushi items
The caloric content of a particular piece of sushi will vary greatly depending on the size of the piece, the part of the fish from which it was cut, and if the fish was marinated or treated in any way prior to serving.
Why is shoyu (Soy Sauce) Black?
Shoyu (soy sauce) is a “fermented” product, which means that when the soybeans, wheat and salt are combined with water, a starter with mold called ‘koji’ is used to convert some of the sugars into alcohol, in a process somewhat similar to making beer. After a period of time, enzymatic and chemical reactions create a liquid called ‘shoyu’ that has darkened due to oxidation (a chemical reaction where oxygen bonds with other compounds, changing their properties).
Why Does Sushi Usually Come As Two Pieces?
The practice of serving sushi in two pieces (ni kan/2 kan) comes from the original edomae-zushi of the 1800’s, the ancestor of today’s nigirizushi. Originally, nigiri-zushi was one large piece, a square. Because it was sometimes difficult to eat, some people began cutting it down the center into 2 pieces. The custom of serving sushi today in a set of two comes from this practice.
Why Is Ginger Served With Sushi?
Traditionally, ginger (gari) has long been served with sushi as it will cleanse the palate when eaten between different kinds of sushi. Ginger also has minor anti-microbial properties and it is thought that eating it with raw food can assist in the prevention of sickness if there is any contamination of the product. Wasabi also exhibits similar characteristics and for that reason, both have stuck as an accompaniment to sushi.
What Makes Seafood Safe To Eat Raw ?
Due to the detailed nature of this question, we have devoted an entire page to the question “what is sushi grade fish?”
Is It Acceptable To Eat Raw Fish That I Buy At The Grocery Store?
Unless your are buying prepared sushi made by trained professionals, this is not recommended. It is a definite risk to eat store bought fish (at the regular seafood counter or area) as sushi due to the higher potential for parasitic or bacterial contamination. Restaurants have sources that are different from the market, and specifically buy food items that are intended to be eaten raw (commonly referred to as “‘sushi grade”). Fish that you buy at the market is intended to be cooked, and is therefore not handled with the same care as what you eat in a restaurant. Anisakiasis is a particularly nasty and potentially fatal infection caused by microscopic larval worms that live in some marine creatures that can be avoided by thorough cooking, or certain deep freezing techniques. Toxoplasmosis has also been found in some raw seafood. While rare, it is one of the many risks inherent in uncooked foods. While some stores now specifically offer “sushi grade” fish in a prepared food section as well as their own sushi bars, it is best not to assume that any fish on display is safe uncooked unless specifically labeled as such and handled properly by professionals.
Can I Freeze Supermarket Fish To Make It OK To Eat Raw?
Most fish that is served in restaurants has been ‘flash frozen’ (which can freeze a fish in seconds to extremely cold temperatures) immediately after being caught, primarily to preserve freshness, but with the added benefit of killing any parasites that the fish may harbor. Unfortunately, your home freezer is not able to freeze a piece of fish as quickly or to as cold a temperature as “flash freezing” and therefore may not kill all parasites. Home freezing also does not deal with other pathogens that might be introduced in the handling process (e.g. bacteria on your counter or at the store) and this can also have a negative effect the texture and flavor of the fish for for the previously mentioned reasons. It is therefore not an accepted practice to freeze fish from the regular supermarket at home to make it safe for consumption raw.
Is Fresh Water Fish OK To Eat Raw?
Another issue that comes up occasionally is the use of fresh-water fish for making sushi. I offer a resounding “NO.” Fresh-water fish can contain bacteria and parasites that are more prolific or potentially dangerous than that found in salt-water fish. Species such as salmon that spend a large portion of their lives in the ocean are generally considered safe, as well as its permanent denizens, but it is recommended that people not eat fresh-water fish raw due to the increased potential for parasites, some of which can be extremely dangerous.
Preparation And Supplies
Where Do I Find More Information About Sushi Preparation?
There are plenty of books available on the subject. There are also Web pages devoted to the topic. Otherwise, see my how to make sushi at home and the preparation guide for more information.
Where Can I Get Sushi Making Supplies?
If you are lucky, there is a Japanese food store or two in your area. I recommend browsing your business phone book for the keyword “Japan” or “Japanese” to try to locate a grocer that may supply you with everything. If unsuccessful, check out any international or Asian food market in your area. If still unsuccessful, most larger grocery stores are beginning to sell supplies you’ll need. If that still doesn’t work, you may mail-order rice, nori, wasabi, etc. from a few places on the Web such as Catalina Offshore Products. We have more specific information on our What Is Sushi Grade Fish And Where Do I Buy It? page for those interested.
What Type Of Rice Cooker Should I Buy?
A rice cooker is not vital when making sushi at home, but a good one sure does make things easier. See my Rice Cooker page for an article on comparing cookers.
Do You Have Any Tips On Preparing My Own Sushi?
My only real suggestion is practice! When making a “maki,” or cut roll, using half a sheet of nori is the right way to go. I remember using a whole sheet the first time I made maki and I had a really big lip. Very strange. I recently added a large section to this website on how to make sushi at home. This includes instructions as to how to make each different type of sushi as well as a preparation guide and tips for making perfect sushi to make all your sushi come out just right.

How Do I Make My Sushi Rice Turn Out Like It Does At Restaurants?
When rinsing Japanese rice to get rid of the excess “dust”, wash and rise the water several times until the water becomes almost to completely clear. This may entail rinsing 4-6 times. Next, Japanese rice needs to be cooked at a ratio of 1 to 1.25 cups of rice to water. Usually western rice is a 1 to 1.5 ratio. Also, after it is done, it needs to steep in its own steam for about 10 minutes with the lid on. When cooking Japanese Rice, the lid never comes off until it is done. If your rice is still “gluey and “starchy” you may have added too much water. Next transfer the rice into a large flat container to cool and dry it quickly, then add the sushi seasonings.
What If I Don’t Have A Rice Cooker?
Gavin, from the alt.food.sushi Usenet group kindly supplied his recipe for what he calls “fail safe sushi rice.”
How Can I Keep The Rice From Sticking To My Hands When Making Sushi?
When cooking short grain sushi rice, be careful to measure the water properly or the rice may turn out too soft (and mushy). After cooking, the rice is always left to cool under a wet towel and the rice consistency will even out after resting (if some grains are slightly undercooked) and cooling a bit. When seasoning, use a cutting motion to mix in the vinegar etc., which will help separate the grains without crushing them. The most important piece of the puzzle is that your hands should be moist but not overly wet when shaping the rice bed, which will help prevent the rice from sticking to your hands. With practice, you should be able to get the neta (what you call the fish on top of the rice) to stick to the rice, however this will not always happen so don’t feel you are doing it wrong if the neta is just balanced on the rice. The hardest part of the whole process is making sure that the rice is made properly so it will stick together without being sticking to your hands instead of itself and making preparation difficult. This skill takes some time to perfect and my advice is to keep practicing and, in time, you will get a feel for it. In Japan, sushi chefs may train in just cooking rice for years before being allowed to prepare the fish, so don’t feel disheartened if you cannot make perfect rice, or if it takes you a while to learn, its is an art as much as a science.
Tipping At A Restaurant (North America)
What is the correct amount to tip the itamae (chef)?
While there is no hard and fast rule that I have come across and traditional sushi dining etiquette is interesting but more cultural than mandatory these days, when I sit at the sushi bar I tend to give most of my tip to the itamae and a small portion to the wait staff who serve me my drinks (since at the sushi bar I order directly from the itamae). In this case, it is my belief that the itamae has done most of the work, and therefore deserves most of the tip (though the wait staff also deserve something for their efforts as well). The actual amount that you decide to tip is entirely up to you.
