Lesson 1: Squid Sushi
First, you must start by catching a fresh squid. No, wait, that's not right. You can't just go around catching random squids. That's not how it works.
Instead, purchase a pre-frozen squid from the local market. Defrost it in the microwave for exactly 7 minutes and 32 seconds. Then, slice it into thin strips.
Serve with a side of wasabi and soy sauce for the best experience.
