Shrimp karaage onigiri with spicy mayo

A small rice triangle with a whole karaage-fried shrimp and a spoon of spicy mayo inside: peeled and curled (tails off), double-fried in a craggy tapioca crust like the karaage page, then closed fully into the rice — nothing sticking out. Shaping basics are on the onigiri page.

Fry while the rice cooks. Shape while the rice is warm — cool enough to hold, never fridge-cold.

Step by step

  1. Rice

  2. Cook the rice

    1Cook the rice

    ~45 min

    For this step

    • Japanese short-grain white rice1½ cups (300 g)
    • Water (for the rice)1⅔ cups (400 ml)
    • Cook the rice in the water — rice cooker or pot (see onigiri). 1½ cups of uncooked rice makes about 660 g cooked: 12 onigiri.
    • While it cooks, fry the shrimp (steps 2–7).
  3. Shrimp karaage

  4. Peel the shell off — leave the tail OFF.

    2Peel, devein, curl

    ~12 min

    For this step

    • Medium shrimp, shell on12
    • Peel the shells and the tails — nothing sticks out of the finished onigiri.
    • Run a skewer under the dark vein along the back and lift it out.
    • Bend each shrimp into a tight C so it sits in a small rice ball.

  5. Marinate

    3Marinate

    20–30 min
    • Mix:
      • soy sauce 1 tbsp
      • sake 1 tbsp
      • mirin 1 tsp
      • ginger, grated 1 tsp
      • garlic, grated 1 small clove
    • Toss the shrimp in it and fridge 20–30 minutes.
  6. Starch board and crumbs

    4Starch board and crumbs

    ~5 min

    For this step

    • Tapioca starch (or potato starch)~60 g
    • Water (for crumbs)1–2 tsp
    • Spread the tapioca starch on a cutting board.
    • Drizzle 1–2 tsp water over part of it and work with a fork into small crumbs and pebbles — same trick as karaage.
  7. Heat the oil

    5Heat the oil

    medium-high~10 min

    For this step

    • Neutral oil (for deep-frying)enough for 3–4 cm depth

    Heat 3–4 cm of oil in a heavy pot to 180 °C.

  8. First fry until pale gold; rest; second fry until dark and crisp.
    First fry until pale gold; rest; second fry until dark and crisp.

    6Coat and fry twice

    180 °C oil~15 min
    • Lift the shrimp from the marinade; shake off excess. Roll each in the starch and crumbs, pressing so the bits stick.
    • First fry: a few at a time, about 1½–2 minutes, until pale gold. Rest on a rack 2–3 minutes.
    • Second fry: back in until deeper golden and crisp, about 30–45 seconds. Drain.
    Coat and fry twice

    7Spicy mayo

    ~2 min

    For this step

    • Japanese mayo (Kewpie)3 tbsp

    ~5 min

    For this step

    • Water (for your hands)a small bowl
    • Diamond Crystal kosher salta little
    • Turn the hot rice into a large bowl to cool a little: warm, cool enough to hold.

    • Scoop about one rice paddle (~55 g) into your left palm.
    • Press a small well in the middle. Lay one curled shrimp in it and add about ½ tsp spicy mayo.
    • Close the rice over it with one gentle squeeze — like a snowball. Nothing should poke out.

    • Cut each nori sheet into 4 strips (12 strips).
    • Lay a strip rough side up and set an onigiri on its middle.
    • Fold both ends up around the bottom so you can hold it.
    Wrap in nori

  15. Serve

    12Serve

    • Eat right away, or within a few hours — wrapped in plastic and then a thick kitchen towel.
    • Don’t refrigerate: the rice turns hard and the crust softens.
