Using clean hands, peel crab sticks into thin strips. Place them in a bowl along with carrots, kewpie mayo, soy sauce, lemon juice, mirin, and sriracha. Stir to combine.
Julienne the cucumber and place it at the bottom of a bowl. Top with a mound of crab mix. Garnish with a few avocado slices, toasted sesame seeds, a quick drizzle of sriracha and kewpie mayo, and tobiko (optional).
Notes
I recommend using your hands to thoroughly mix your ingredients together.
If you love sushi, try garnishing your Kani salad with nori or furikake.
You can make Kani salad 3 to 5 days in advance, but of course, the fresher it is the better it will taste!
You can use regular mayo if you don't have Kewpie, but I promise that Kewpie is worth all the hype! You'll never want to go back.
