Instructions

1. 1

   Soak the rice

   Put the rice in a large bowl, cover it with water and leave it to soak for 10 minutes. Rinse until the water runs clear.

2. 2

   Cook the rice

   Put the rinsed rice in a saucepan and add the measured 360 ml water. Cover, bring to the boil over a high heat and cook for 5 minutes. Reduce the heat and simmer for 10 minutes, until the water has been absorbed.

3. 3

   Season the rice

   Leave the rice covered. Stir together the rice vinegar, salt and sugar in a small jug or bowl. Transfer the rice to a large shallow dish or tray, pour over the vinegar mixture and gently fold it through with a large spoon until evenly distributed. Leave to cool.

4. 4

   Make eel sauce

   Put the soy sauce, mirin, sugar and water in a small pan and mix. Bring to the boil and cook for 10 minutes, then take the pan off the heat. Set aside; the sauce will thicken as it cools.

5. 5

   Mix spicy mayonnaise

   Combine the mayonnaise, sriracha, pinch of sugar and ¼ tsp rice vinegar in a small bowl. Set aside.

6. 6

   Prepare dipping water

   Mix the ¼ cup water and 2 tsp rice vinegar in a medium bowl large enough to dip your hands into. Set it aside.

7. 7

   Arrange the nori

   Place a sheet of nori, rough side up, on a rolling mat.

8. 8

   Spread on rice

   Dip your hands in the vinegar water, then spread an even layer of rice over the nori, reaching the edges and corners.

9. 9

   Add the filling

   Turn the sheet over and arrange the fish or imitation crab, avocado and cucumber along the bottom edge of the nori.

10. 10

    Roll the sushi

    Roll tightly until the bottom edge of the rice meets the nori. Place the bamboo mat over the roll and squeeze it firmly.

11. 11

    Make more rolls

    Repeat the rolling process with the remaining ingredients to make 3 more rolls.

12. 12

    Add the toppings

    Drizzle each roll with eel sauce and sriracha mayonnaise. Cover the tops with an even layer of crispy fried onions.

13. 13

    Slice and serve

    Wet a sharp knife blade and cut each roll into 8 even slices: halve the roll, then halve each section twice. Serve straight away with soy sauce, wasabi and sushi ginger, or refrigerate for later.

What is a California roll?

The California roll is a Japanese-American style of sushi, commonly filled with crab, avocado and cucumber. Its familiar combination brings together mild seafood, rich avocado and crisp vegetables.

This version uses a nori-wrapped roll with rice on the inside, then adds eel sauce, spicy mayonnaise and crunchy onions. Those toppings give the cool filling a sweet-savoury finish and a crisp contrast.

Nutrition and macros by portion

The nutrition label shows one serving as written: 483 calories, 8g protein, 81g carbs, 14g fat.

Most of the carbohydrates come from the sushi rice, while avocado, mayonnaise and crispy onions contribute much of the fat. The imitation crab or fish supplies some protein, though the rice remains the main component of the meal. Balance the plate with extra cucumber or a side of greens.

Choosing the filling

Crab: Imitation crab sticks are convenient and have a mild, slightly sweet flavour. Sushi-grade salmon or tuna can be used instead, as the recipe suggests.

Avocado and cucumber: Choose a ripe avocado that still holds its shape when sliced, and remove the cucumber seeds so the filling stays less watery.

Seasoning the rice

Rinsing: Wash the rice until the water is clear, then drain it well before cooking. This helps the grains cook evenly without excess surface starch.

Folding: Mix the vinegar, sugar and salt before adding them to the cooked rice. Fold gently rather than stirring hard, so the grains stay intact.

Rolling a neat sushi roll

Sticky hands: Dip your fingers in the vinegar water before spreading the rice. Re-dip as needed to reduce sticking, without letting the rice become wet.

Firm roll: Keep the filling near the bottom edge and roll it up tightly. A firm, even squeeze with the bamboo mat helps the roll hold together when sliced.

Checking the sauces

Eel sauce: Simmer the soy, mirin, sugar and water for the full 10 minutes, then let it cool. It thickens as it stands, so judge its consistency after cooling rather than while hot.

Spicy mayonnaise: Mix the ingredients until smooth and drizzle it over the rolls just before serving. Add the crispy onions last to preserve their crunch.

Serving and timing

The recipe takes about 40 minutes overall, including soaking and cooking the rice and assembling the rolls. While the rice cooks, the eel sauce and spicy mayonnaise can be prepared.

Serve the slices with soy sauce, wasabi and sushi ginger. A simple salad or lightly dressed greens can round out the meal without competing with the sushi.

Recipe notes & tips

• Let the seasoned rice cool before rolling so it is easier to handle.
• Keep the rice layer even and avoid packing it too thickly.
• Cut the avocado and cucumber into similar-sized sticks for easier rolling.
• Use a damp, sharp knife and clean the blade between cuts if rice begins to stick.
• Drizzle the sauces and add the crispy onions just before serving.

Variations

• Salmon filling: Use sushi-grade salmon in place of the imitation crab for a different seafood flavour.
• Tuna filling: Swap in sushi-grade tuna as the recipe allows.
• Extra cucumber: Add more cucumber sticks for a fresher, crisp filling.
• Milder topping: Use less sriracha in the mayonnaise for a gentler heat.
• Sauce on the side: Serve the eel sauce and spicy mayonnaise alongside for diners to add their own.

Common mistakes to avoid

• Skipping the rinse: Unrinsed rice can cook up overly sticky; rinse until the water runs clear.
• Stirring the seasoned rice: Vigorous mixing can mash the grains; fold the vinegar mixture through gently.
• Overfilling the nori: Too much filling makes the roll difficult to close; keep the ingredients in a compact strip.
• Loose rolling: A slack roll may fall apart when sliced; use the mat to squeeze it firmly.
• Cutting with a dry blade: Rice can cling to the knife and distort the slices; wet the blade before cutting.

How to store

For best texture, serve the rolls immediately. If needed, refrigerate them in a covered container and eat within 1 day; the rice may firm up and the crispy onions will soften. Keep the sushi ginger and dipping sauces covered separately.
