Mix all the ingredients together, preheat your pan on low heat and oil it. For the soy sauce, you can take the classic salted kikkoman sauce or the reduced salt soy sauce, it's actually what we do and it's very good.
When hot, place a thin layer of your mixture on the pan.
Once you see that the layer is starting to cook but the top is still slobbery, start rolling it up with your Japanese chopsticks and spatula.
Repeat until you have no more mixture.
You will then get a nice tamagoyaki roll.
Place this roll on the makisu (sushi mat) and roll it up tightly but without crushing it. Hold it together with rubber bands.
Wait for it to cool to room temperature and do not put it in the fridge. Then remove your sushi makisu mat and cut your roll into 3cm slices.
Your tamagoyaki is ready to be eaten! Enjoy your meal!
