Here are some tips and guidelines for sushi etiquette, holding those pesky chopsticks, using wasabi and ginger, and the different types of sushi. (Images are not mine)
Basic Sushi Etiquette
Ginger & Wasabi
⇒ Sometimes, the sushi chef has already placed some wasabi underneath the sliced fish.
⇒ Don’t be shy about using your hands for nigiri and maki rolls.
Types of Sushi
⇒ Edomae sushi is my personal favorite. Simple and delicious!
