The more you know about Sushi, the more fun it becomes. Here are a few pointers.
Hosomaki is a small Maki roll, wrapped in seaweed with rice and the filling on the inside. These are perfect bite-size pieces.
Nigiri is a block of sushi rice with a topping such as prawn, fish, or vegetable. Nigiri has an iconic look that's instantly recognisable as sushi.
California Roll doesn't sound very Japanese but it's very popular. This is an 'inside out' roll, with sesame seeds and rice on the outside and seaweed and filling on the inside. These come in larger and smaller bites.
