blank
In a bowl, combine crab meat, mayonnaise, sriracha, and soy sauce.
Gently fold in diced avocado and taste and adjust seasoning if needed.

Cook rice according to package.
Stir the rice vinegar, sugar and salt together and fold gently through the cooked, warm rice. Let it cool slightly before shaping.

To assemble the onigiri balls, wet your hands with water and lightly rub with salt (to prevent sticking and help preserve the rice).
Take about ¼ cup of rice and flatten it slightly in your palm.
Place 1 tablespoon of the spicy crab-avocado filling in the center.
Gently shape the rice around the filling into a ball or triangle, sealing it in.
Sprinkle with sesame seeds or furikake, drizzle with more kewpie mayo and sriracha, and top with avocado.
Serve with soy sauce, pickled ginger, and wasabi on the side if desired.
