Spicy tuna rolls are one of my favorite foods, but good grief they’re difficult to make at home! Not only does the rice have to be the perfect stickiness, but then you have all the rolling and pressing. For these appetizers, I wanted that same flavor but with half of the effort. Thus these spicy tuna bites were born.

Actually the “spicy tuna roll” did not even originate in Japan, but in LA. It was essentially a good way to use up the parts of tuna that weren’t prime enough for nigiri. According to one of the chefs in The Story of Sushi, they actually used Tex-Mex chili sauces to make the spicy mayo when this became popular in California. How resourceful!

Ingredients

Sushi Grade TunaFor these spicy tuna bites, unless you want to cook your tuna all the way through, you want to make sure to use a high quality tuna. If you prefer to not sear it at all, I would look into sushi/sashimi grade, which can typically be found in the freezer section at Whole Foods. Ahi, yellowfin, and sashimi will all work fine. If you prefer your tuna more on the rare side, stick with searing 1 minute per side. For medium rare, 2-3 minutes per side will work best.

Watermelon Radish – This is a large radish that’s light green on the outside and pink on the inside. It’s the perfect size for these! It can be tricky to find these sometimes and regular radishes are quite small. If you can’t find watermelon radish, good substitutes would be sliced jicama, cucumber, rice cakes, or wonton chips.

Spicy Mayo Options

  • For store-bought mayonnaise I like to use either Sir Kensington’s Organic or Primal Kitchen’s Avocado Oil Mayo (btw this is super cheap at Costco). You can also make your own mayo using this recipe.
  • My favorite clean sriracha is Lingham’s or Underwood Ranches. 
    If you can tolerate rice vinegar, Fix is another good one.
  • You may be able to find other local brands in store that are fine, just check your labels. Of course Tabasco is a good alternative as well.

    Too funny, you’re a mind reader! I was just craving sushi and researching what type of fish to use this weekend. Although I’ve been known to advocate for the same fish you mentioned at Whole Foods – apparently there is no standard for what “sushi grade” fish means! So it could mean everything or nothing. Just FYI for anyone curious about the topic:

    According to the great world of the web, large species of tuna do not contain parasites. After extensive searching, I found this FDA document that seems to support that concept. https://www.fda.gov/downloads/Food/GuidanceRegulation/UCM252383.pdf

    Although it appears to be safe, I personally still feel a little uneasy with trusting that. I found these FDA guidelines on how to make any type of fish safe and free from live parasites! I’ve set my freezer to -21 degrees Celsius and will wait until next weekend now 😀
