If you're new to making sushi, please see the Sushi Beginner's Guide before getting started! This includes guides to all the basics, FAQ, and how to source ingredients. This site focuses on Americanized/Westernized sushi, check out the Types of Sushi page to learn more!
The Umami Tsunami roll is a Crafty Cookbook original sushi roll. It has shrimp tempura and avocado on the inside, topped with tuna, yakiniku sauce (Japanese BBQ sauce), and green onions. This roll is one my favorites on the site! The Japanese BBQ sauce is so delicious on the tuna, and the crunch from the tempura gives the roll a great texture.
You can control how much tuna you want to use on top, check out the How to Top Sushi Rolls guide to read more on that!
Ingredients & Substitutions
Don't forget to check out the guides on Buying Fish For Sushi and Buying Other Ingredients for Sushi if you're not sure where to find what you need! I include online product links for reference, but it's typically much cheaper to purchase these items locally, so check out your local options!
Thinly sliced maguro (bluefin) tuna
- Make sure you're using tuna that is safe to eat raw (more info)
- Try substituting other fish such as yellowtail, salmon, or red snapper
- Check out How to Slice Fish for Sushi if needed
Shrimp tempura
- You can purchase premade frozen shrimp tempura from an Asian grocery store or Trader Joe's.
- If preparing from frozen, follow the package instructions to heat in an oven, air fryer, toaster oven, or deep fryer. (I typically prepare frozen shrimp tempura in an air fryer)
- Allow the shrimp tempura to cool down for a few minutes before placing in the roll.
- If desired, cut the tails off of the shrimp before placing in the roll.
- Shrimp tempura can be made from scratch at home, but I don't have a guide to that at this time.
Avocado slices
- Slice the avocado into ~¼" thick pieces. You should use about ~⅙th of a medium avocado.
- It's best to use a perfectly ripe avocado if you can. Ripe avocados will be slightly soft when pressed, but not mushy.
- I like to buy my avocados while they're still hard, then transfer them to the fridge once they're perfectly ripe. Avocados ripen much slower in the fridge.
Yakiniku Sauce
- This is also known as Japanese barbecue sauce, it's commonly brushed onto grilled meats. It has a savory (umami) flavor that pairs very nicely with tuna.
- You can find it at your local Japanese market, some regular US groceries stores, or online (link).
Green onions
- Thinly slice the green portion of the green onion for this recipe.
- Green onions go by many other names including: scallions, spring onions, salad onions, and green shallots.
- Cut at an angle to create the style pictured.
Sushi rice
- Sushi rice is prepared, medium grain rice that is seasoned with rice vinegar, sugar, and salt. The seasoning added to the rice is what give it the distinctive taste and sticky texture.
- If possible, I strongly recommend picking up the proper kind of rice rather than using whatever rice you have on hand. Other varieties of rice (jasmine, basmati, etc.) will not turn out the same.
- Follow my recipe for Simple Sushi Rice before you begin making your sushi. You can find more information there on locating the proper ingredients.
Nori
- Nori is the seaweed wrapping used to hold together sushi rolls. After opening, store leftover nori sheets in an airtight bag at room temp with all the air pressed out to maintain freshness.
- Packages of nori vary a lot in quantity and price. I've tried out a variety of brands at different price points and have been happy with all of them. I don't think you need to splurge on the more expensive brands.
- A Japanese grocery store will have the widest selection of nori. You may be able to find nori in the "Asian foods" section of a large American grocery store, but you can also find nori online if needed.
- Nori comes in a variety of sizes, so make sure you pick up full sheets (approximately 8"x7"). These sheets can be cut down smaller when making rolls (if desired). You can read more about this in the How to Make Sushi Rolls post.

- Place the roll on a cutting board and grab your sharpest knife. Optionally, cover the roll with plastic cling wrap. Run the knife under water for a second, then shake off any excess. Cut the roll into 8 equal pieces using a gentile sawing motion with the knife, running the knife under the tap between every 2-3 cuts to prevent sticking. (click for guide)
- Plate the roll on your serving dish. Drizzle or brush the yakiniku sauce over the tuna then top with green onion. (click for guide)
