Good nonstick tamago or crepe pan (I'm using a great square pan bought from a local store called Marukai
- which is luckily not too bad a drive away from me).
You'll also need either chopsticks or a whisk to scramble the eggs, I prefer chopsticks because a whisk might make the eggs too bubbly.
A bowl to mix the ingredients
I also use a wide spatula and sometimes a small silicone spatula to help roll the omelette.
A sharp knife.
