Onsen tamago (Japanese: 温泉卵 or 温泉玉子) is a traditional Japanese low temperature egg which is originally slow cooked in the water of onsen hot springs in Japan. The egg has a unique texture in that the white tastes like a delicate custard (milky and soft) and the yolk comes out firm, but retains the color and creamy texture of an uncooked yolk. This special texture is the result as egg yolk and egg white solidify at different temperatures. The egg is poached within the shell and is served with the shell removed in a small cup with sauce of broth and soy sauce.
The traditional way of cooking onsen tamago is to place eggs into rope nets and leave them in a hot spring, with water that is approximately 70 °C (158 °F) for 30 to 40 minutes. Crack open the shell and serve the egg in seasoned bonito dashi (Japanese stock) for breakfast, or in a light sauce made with mirin, dashi and soy sauce with chopped spring onions sprinkled over the top.
