Sushi is a traditional Japanese dish that typically consists of vinegared rice combined with various ingredients, including raw fish, vegetables, and seaweed. There are several types of sushi, such as nigiri (slices of fish on rice), maki (rolled sushi), and sashimi (slices of raw fish without rice). To enjoy sushi, beginners should start with milder flavors, like California rolls or cooked shrimp. It's also important to use soy sauce for dipping and wasabi for added spice. Sushi can be enjoyed in restaurants or made at home with simple ingredients and tools, making it accessible for everyone.
