Transfer freshly cooked rice immediately into a bowl while it is at maximum heat. No resting. The rice must be very hot throughout — steam should rise freely from the surface.

Break the egg onto the rice. Pierce the yolk first and break it, then fold the white partially through the rice without fully homogenising the two. This is where the dish lives or dies: over-mixing collapses the textural distinction between yolk and white and produces a uniform paste; the goal is a varied coating in which streaks of yolk and incompletely incorporated white remain visible against the grains.

Add the soy sauce in drops across the surface. Fold once or twice more — not to combine fully, but to distribute the seasoning. The heat of the rice will have partially set the white while leaving the yolk fluid; the resulting coating should be sauce-like rather than liquid.

If using katsuobushi, scatter the flakes over the surface immediately before eating. The residual heat of the bowl will cause the flakes to wilt and curl at the edges — the point at which they are ready.
