i like sushi alot,
but never had absolutly sofisticating suhi in restaurant, this is the reason i eat sushi almost only at home.
the reasons are:
- it starts with the rice, most use califirnia-raised rice, wich isnt bad but isnt really good!
- the rice-vinegar, non restaurant care about the quality of this ingridience and the differenc between a industrial vinegar and the one from the manufacture murayama is huge.
- most restaurants don't use the ceder-bowl to stir the rice adding the salt-sugar-vinegar-mix,
and forget that the bowl is not just a bowl but it is also an ingredience!! a hint of the ceader-taste gos to the rice and this is always missing. btw. i use only "gray-sea salt".
- most restaurant don't use a piece of combu for cooking the rice!
- all restaurants have a terrible soy-sauce! most use the terribly tasting kikioman, i use at home 5 years, duble brewed, ripend in original/traditional ceder-casks, "shoyu" soja-sauce from the manufacture inoue, this is worth to be added a sushi.
- most restaurants do use wasabi, what are i am saying, most use a green paste with 0% wasabi!
ingredience are comon horseraddish, mustard and color. it is hard to find a 100% wasabi, i use a powder witch i was told by a japanese sushi-fan that it is the one that has the more similar taste to a fresh real wasabi but still comes not even close (i tell you about him because i have never had a fresh wasabi in my hand an on my tonge).
- i'm still searching a better nori-leaves, when i find one i'll post. the best i have is original frm japan and has a fresher, jodine taste, most taste like wet cardbord.
my favorite sushi is toro, thuna, wild salmon, bonito (which is a thuna-family).
i have ti taste fugu once in my life

.
and i like sashimi !!
the only problem at home (i meen in switzerland) is to get really, really fresh fish

,
tuna is not a problem because it has to be ripend, but salmon and other fresh sea-fish is extremly difficult.
