Tamago-zake is a kinda of egg nog in Japan. The ingredients were egg, the liquid of ginger, sugar, and sake. This time, I mixed all in a sauce pan, and put it in hot water to heat it up(We call this technique "Yusen" in Japanese). It tastes milky and creamy. little vanilla flavor, I think. People drink it when they get a cold. It's said a very effective hot drink.
