Tamagoyaki 卵焼き (literally 'grilled egg', also called tamago or dashimaki) is a type of Japanese omelette, which is made by rolling together several layers of cooked egg. These usually are prepared in a rectangular omelette pan called a makiyakinabe.
There are several types of tamago. Tamago is made by combining eggs, rice vinegar, and sometimes sugar or soy sauce. Additionally, sake is used in some recipes. An alternative version includes a mix of shrimp puree, grated mountain yam, sake and egg, turned into a custard-like cake.
Tamago is served around the world in the form of nigiri, and also appears in many types of sushi rolls. In Japan, it is served as a breakfast dish.
The above is the ideal but not having the required makiyakinabe I had to do with my own medium sized frying pan and a recipe from justbento.com for a 1 egg version of the food.
The full recipe is on the TAB at the top of this page.
I really find this so much more tasty than a plain omelette probably because it tends to be slightly sweet. The perfect versions are rolled whereas in my recipe they are folded. If you are serving this hot with a main meal as added protein make sure everything else is ready, it only takes about a minute and a half to cook.
