Combine the milk, salt, and the egg. Strain the egg mixture really well. In a skillet, make a very thin egg omelet. Place it onto plastic wrap and let it cool.
Set aside some ketchup flavored rice for the ears and hands. Place cheese in the center of the remaining ketchup rice and wrap in plastic wrap to make a round rice ball. Make the eyes and hands using plastic wrap also.
Coat the top visible part of the ketchup rice with the thin egg omelet. Wrap in plastic wrap while adjusting the shape of the face a little. Let it sit until settled.
Make the face parts with the nori and boiled carrot. Fill the bento box in the order of the face, other bento fillers, eyes and hands, and the other parts of the face and it is done. Make a twinkle in each eye with a small amount of mayonnaise.
Story Behind this Recipe
I wanted to make Pikachu with just one egg.
Cut a few slits into the edge of the thinly cooked omelet for easy handling. After forming the rice into the Pikachu face, cover it with plastic wrap and place the face parts on top of it to see if you need to adjust the shapes, such as the size of the eyes.
