Tamagoyaki

Whisk the eggs gently in a bowl, being careful not to create too many bubbles. Add dashi stock, sugar, mirin, soy sauce, and salt, mixing until the seasonings are fully dissolved and incorporated.

Heat a rectangular tamagoyaki pan over medium-low heat and brush lightly with oil using a folded paper towel. The pan should be hot enough that a drop of egg mixture sizzles gently on contact.

Pour a thin layer of egg mixture into the pan, tilting to spread evenly across the entire surface. When the egg is about eighty percent set but still slightly moist on top, begin rolling from one end.

Push the rolled egg to one end of the pan, re-oil the empty surface, and pour another thin layer of egg. Lift the rolled portion slightly to let new egg flow underneath, creating a continuous connection.

Roll the existing log back over the new layer once it is mostly set. Repeat this process of pouring, setting, and rolling four to five times until all the egg mixture is used up.

Remove the finished tamagoyaki from the pan and shape it by pressing gently with a bamboo sushi mat. Let it cool for five minutes before slicing into rounds that reveal the spiral layers.
