Break the eggs into a bowl and beat until the whites and yolks are fully combined but not aerated. For atsuyaki, add the sugar, mirin, and usukuchi and stir until the sugar dissolves completely. For dashimaki, add the dashi, sugar, and usukuchi. If using mitsuba, fold it in at this stage. The mixture should be uniform and pale — no visible streaks of white.

Set the tamagoyaki-ki over medium-low heat. Lightly oil the surface with a folded paper cloth or brush. The pan is ready when a drop of egg mixture sets gently on contact without sizzling aggressively or colouring — pale, quiet cooking is the target throughout.

Pour a thin layer of the egg mixture into the pan — enough to coat the base. This is the step where the dish lives or dies: the layer must be thin enough to roll cleanly and must be only partially set before rolling begins — the surface should still show a faint wet sheen in the centre when rolling starts. A thick layer will not adhere to subsequent layers and will crack; a fully set layer will not bond. Lift and roll the egg from one end of the pan to the other using chopsticks or a spatula, forming the first roll. Push the completed roll to the far end of the pan.

Oil the now-empty section of the pan lightly. Pour a second thin layer of egg mixture in, lifting the existing roll briefly to allow the new egg to run underneath it. When the new layer is partially set with a faint wet sheen, roll the existing log back over the new layer, incorporating it. Push the roll again to the far end. Repeat with remaining egg mixture, building the roll layer by layer until all egg is used. At no point should the surface brown or bubble — pale gold throughout.

Remove the finished roll from the pan and place it immediately on a makisu (bamboo rolling mat). Roll the mat firmly around the tamagoyaki and press, shaping it into a compact rectangle. Hold or secure for 5 minutes. Without this step, the roll relaxes into a cylindrical form and the rectangular shape is lost. The roll should feel firm and hold a clean rectangular cross-section when the mat is removed.

Unwrap and slice into portions approximately 2 cm thick. The interior should show distinct, pale golden layers bonded cleanly to one another. Atsuyaki will be dense and firm; dashimaki will tremble slightly and appear more tender. The cook's test: the off-cut tail piece from the first roll, eaten immediately, reveals whether the seasoning is correctly balanced.
