Step-by-step cooking
-
Step 1

Put 2 loosely filled paper cups of cooked rice, about 300 g, in two bowls. If using chilled rice, reheat until piping hot throughout, about 74°C when checked. Drain the canned tuna thoroughly and flake it with a fork. Thinly slice the spring onion; keep the mayonnaise cold.
-
Step 2

Beat the 2 eggs in a small bowl. Mix 2 level teaspoons soy sauce, 2 level tablespoons water and 1/2 level teaspoon sugar in another bowl until the sugar dissolves. Keep the tuna separate from this sauce.
-
Step 3

Heat a nonstick pan over medium-low heat with 1 level tablespoon neutral oil. Add the beaten eggs and stir gently for 1–2 minutes, until fully set with no liquid egg. Transfer to a clean plate; do not leave the eggs undercooked.
-
Step 4

Pour the soy mixture into the same pan. Simmer over low heat for about 30–45 seconds, just until hot. Keep it loose enough to spoon over rice; if it reduces too far, add 1 level teaspoon water rather than burning it.
-
Step 5

Divide the cooked eggs and drained tuna over the hot rice. Spoon half the sauce over the bowls first, then taste and add the rest only if needed. Keep the tuna in a visible mound rather than mashing it into the rice.
-
Step 6

Drizzle each bowl with 1 level tablespoon mayonnaise. Finish with the sliced spring onion and crumbled seaweed, if using. Serve immediately and stir together at the table. Do not return the mayonnaise topping to the hot pan.
Finished dish

Makes 2 modest bowls. The 15-minute time starts with cooked rice and prepared ingredients; cooking rice, thawing frozen ingredients and cooling fresh rice take extra time. A paper cup means 180 ml and is filled loosely. Use a level 15 ml tablespoon and a level 5 ml teaspoon. Never leave cooked rice at room temperature for hours. Cool leftovers promptly, refrigerate and reheat only once until piping hot throughout; use refrigerated rice within 24 hours. For reheated rice, check for 74°C if using a thermometer. Contains fish and egg; mayonnaise may contain egg and soy sauce may contain soy and wheat. Use canned light tuna if you prefer a milder flavour. The cooked egg, drained tuna and mayonnaise are separate toppings, not a raw-fish preparation.
Enjoy every bite
How to enjoy it
Mix just a little of the topping into each spoonful rather than stirring the entire bowl at once. Keep some seaweed aside for a crisp final sprinkle.
