If you like Japanese and Oriental food, if you love seafood, if you want to impress your friends with your complex knowledge of a complicated traditional process, then you should really learn how to make sushi.
Let's just face it - sushi is not just another dish, it's a part of the modern culture, right there, between Darth Vader and the Beatles.
Your only excuse not to know how to make sushi is if you are allergic to seafood - and even then, it could be nice of you to prepare it for somebody else.
The first thing you should know is that it's not immensely complicated.
On the contrary, the base of sushi is the Japanese minimalist tradition, meaning that you won't need a whole lot of things to prepare it.
You may not be able to make great sushi, but you should be able to accomplish a fairly decent dish from the first attempt (after all, this is what you'll get in most restaurants anyway).
The second thing you should learn before discussing how to make sushi is that it's healthy. It has rice, fish and algae - and nothing deep fried anywhere - it has to be one of the healthiest fancy choices available today.
You will need a cutting board and a sharp knife - two vital tools in this process.
If you've never sliced fish before, maybe you should practice before getting into this!
You will also need rice, rice vinegar, fish/seafood/vegetables (or all of them), Nori seaweed, sugar, wasabi (Japanese horseradish sauce), soy sauce and ginger (not the root, but a pickled ginger, sliced thinly, also called gari).
If you're already confused, don't worry - you will find all of them in an Asian store or in any major supermarket, usually all these ingredients are together on the same shelf.
