These Spicy Tuna Bites make a great healthy snack. A low carb, Whole30 appetizer, and paleo-friendly as well as dairy and gluten free, they're quick and beautiful!
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!
Sushi Grade Tuna - For 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.
