If you've never tried sushi before, it can seem a little intimidating. First, there's the whole raw fish thing—can it really be safe to eat? Secondly, how would you order something if much of the menu was in Japanese? Finally, what about handling those chopsticks—you'd rather not have to ask for a knife and fork.

We want to help teach you how to eat sushi, so we put together this guide for you learn a little sushi etiquette, the difference between sashimi and nigiri, and whether or not all these raw fish constitutes a healthy meal.

HOW TO ORDER SUSHI?

You'll likely be given a sheet of paper with available sushi to eat and a pencil to mark your selection. Simply mark "1" next to any sushi you want.

• For the best experience: Sit at the bar, where you can talk to the chef and get his or her recommendations.
• For the best meal: Order a little bit of everything, a few nigiri, a few maki, and a few sashimi. Don't know what those are? Read the next section.

SUSHI VS SASHIMI: WHAT'S THE DIFFERENCE?

Sushi is (typically) raw seafood and other vegetables that have been wrapped up in vinegary rice or seaweed. Sashimi is only the seafood–no rice or seaweed.

• There's a third option: Nigiri. This is a little bit of both. It's a piece of seafood that lays on top of a bed of rice.
• Maki is the name for a sushi roll, typically six or eight pieces of sushi that's served together.
• You might also see temaki, which is sushi rolled inside a seaweed cone.

WHAT ARE OTHER TYPES OF SUSHI?

If you scan the menu, there might be dozens of types of sushi and Japanese vocabulary you don't recognise. Let's clear up what means what:

• Tako: Octopus (this is also the name of a knife the chef uses)
• Toro: Tuna, though you might also see tuna called maguro or magura
• Uni: Sea urchin (pronounced "oo-nee")
• Sake: Salmon...although this is also the word for fermented rice wine.
• Nori: The seaweed typically used to wrap sushi
• Unagi: Freshwater eel, always cooked
• Ebi: Shrimp, always cooked

Tobiko: Roe, i.e.those little orange eggs that provide texture on top of some sushi

WHAT'S A CALIFORNIA ROLL? (OR A PHILADELPHIA ROLL?)

As their names imply, both of these popular rolls were created in America, and you won't find them in Japan. But don't feel ashamed about ordering either!

• California roll: Avocado, imitation crab, and cucumber
• Philadelphia roll: Cream cheese, avocado, and salmon

HOW TO USE CHOPSTICKS

This can be tricky, but you'll get it down with practise. Here's how to get started:

1. Rest one chopstick in between your thumb and pointer finger, and on top of your ring finger. The skinnier end should be pointed towards the food.
2. Hold the other chopstick with your thumb and pointer finger.
3. The first chopstick is an anchor and doesn't move. Move the second chopstick instead, using it to grip the sushi.

SUSHI ETIQUETTE TO KNOW

For the most part, all you have to do is dip your sushi in soy sauce and enjoy. But if you're headed to Japan or dining at a fancy sushi restaurant, you might want to follow these rules:

• Chopstick etiquette: Don't rub the sticks together, and don't stick them upright into your sushi or rice.
• There will be a few slices of ginger on your plate. This is for cleansing your palate, and not to be eating with sushi.
• When eating nigiri (a piece of fish on a bed of rice), use the fish side to dip into the soy sauce, instead of getting your rice soggy.
• If your meal is omakase style, it might be considered impolite if you don't eat every piece of sushi (see our guide to omakase below)

Skip the to-go box. Sushi isn't one of those foods you eat as leftovers.

IS SUSHI HEALTHY?

It depends on what and how many sushi you order. If you want to eat sushi that's good for you, stick to salmon and tuna maki or sashimi.

• What's not healthy? Any roll that's been fried, uses lot of mayo, or cream cheese.
• Instead of mayo, use wasabi. It's high in antioxidants, and it'll add flavour to your meal.
• Choose the low-sodium soy sauce, especially if you're watching your salt intake.
• Is it safe? Eating any raw food carries some risk, but that risk is greatly reduced if you eat at a reputable restaurant, where the chef knows how to safely prepare your food.
