japanese sweet rolled omelette

there are quite a few versions of "rolled omelette." i grew up with savory korean versions (with finely chopped vegetables or dried seaweed in between the layers), but this sweet japanese version has become my new favorite. you only need (5) ingredients, no prepping, and once you get the hang of rolling, it is quite easy to make. delicious by itself, delicious with rice, it is a popular japanese bento item and sushi topping.

japanese sweet rolled omelette (tamagoyaki)

ingredients:
(6) eggs
(1) Tbsp. soy sauce
(1) Tbsp. sugar
(3) Tbsp. water
cooking oil

directions:
1 (option a). in a bowl, beat (6) eggs with a pair of chopsticks or a fork. add (1) Tbsp. soy sauce, (1) Tbsp. sugar, and (3) Tbsp. water and mix well. then strain the egg mixture through a sieve. this is more common way to prepare the mixture.
OR....
1 (option b). in a blender, add (6) eggs, (1) Tbsp. soy sauce, (1) Tbsp. sugar, and (3) Tbsp. water and blend for 5 seconds on high speed - just enough to break the yolk and incorporate the ingredients. skim off any frothy foam on top. i prefer this option as it is quicker and there is less clean-up to do.
2. heat up a pan (i am using a 9.5"x9.5" square pan) and add about (1) Tbsp. of cooking oil. using a clean napkin or paper towel, evenly coat the surfaces and wipe off any excess oil. lower the heat to medium or medium low, add a small ladleful of the egg mixture into the pan and tilt it around to spread evenly approx. 1/8" thick. pop any air bubbles and when it is set on the bottom, but slightly undercooked on top, push it to one side of the pan with a spatula.
3. add more oil, evenly coat the pan surfaces and wipe off any excess oil. add the next ladleful of the egg mixture and spread evenly. lift the bottom of the cooked roll and tilt your pan, so the egg mixture flows underneath it. pop any air bubbles and when it is set on the bottom, but slightly undercooked on top, carefully roll it to the opposite side with a spatula.
4. repeat step 3 until the egg mixture is all used up.
5. (optional) transfer the omelette on to a sushi mat and roll it tightly with the mat and secure with rubber bands. set aside and let it cool.
6. gently unroll, slice and serve. I find the flavor is best when chilled in the refrigerator for a few hours.

yield: (1) 2" wide x 9.5" long x 1" thick rolled omelette
