Welcome to the site Tomas. Sashimi is actually a Japanese delicacy. It's quite simple because it's just raw seafood, that has been sliced into bite-sized pieces. It is typically served with soy sauce and wasabi paste. Pickled ginger is also served as a palate cleanser between bites.
There really isn't a "recipe" to speak of, you simply buy really fresh "sashimi grade" fish.
If you are buying fish with the intention of eating it raw, there are a few things you should know:
- Don't buy from a supermarket
- Buy it from a fishmonger, preferably one you know and trust
- Make sure you let your fishmonger know that you intend to eat your purchase raw.
- Bring a little cooler with some ice to the store with you, take your fish home in this.
If you have concerns about the safety of eating raw fish, you can find more info in the answers to this question: Is it safe to eat raw fish?
Cutting sashimi is rightfully considered an art. Sushi chefs in Japan go to school and apprentice under masters to learn all the intricacies involved. You can approximate in your home, and it will still taste great, but won't be as pretty.
Here are some common, and popular cuts you should try:
- Salmon (Sake)
- Squid (Ika)
- Shrimp (Ebi)
- Bluefin Tuna (Maguro)
- Fatty Tuna (Toro)
- Yellowtail (Hamachi)
- Scallop (Hotate-gai) my favorite!
