Check the size of your tuna can (we need 300g - so use 2 or 3 cans). Open the tuna cans and drain out the liquid. Empty the tuna into a large mixing bowl.
Next, finely dice ½ an onion and a small piece of carrot (about a pinky finger-length size). Add both to the mixing bowl.
Then finely dice 3 stalks of green onion (scallions) - add it to the mixing bowl
[Optional ingredient: Finely dice ½ a chili pepper (discard seeds) - add it to the mixing bowl]
Crack 3 eggs into the mixing bowl.
Then season with 5 big pinches of salt. Followed by 5 cracks of black pepper.
Thoroughly mix everything together.
Finally, we'll add in All-Purpose Flour (2 Tablespoons). Mix it together well. The batter will be sticky now.
