When consumed, ambrosia usually tastes like a delicious delicacy that the customer enjoys. Percy preferred warm chocolate chip cookies, whereas Piper preferred the black bean soup her father used to make for her. Both foods are described as tasting like heaven on earth. In addition to its sweet flavor, ambrosia also has many healthy properties. It gives those who eat it strength and energy; however, too much of it can be harmful. It has been known to cause people to act recklessly and get into fights, so it is not recommended that two people eat the same amount of ambrosia at once. The only negative effect ambrosia has on those who consume it is that it can make them want more of it. Even though it is not healthy, people often overeat this food because it is tasty and provides them with something to satisfy their cravings. Ambrosia was first mentioned in The Lost Hero by J.K. Rowling. This book takes place in modern-day London, where Harry Potter is living after being expelled from Hogwarts. While sitting in Madam Puddifoot's Parlor of Magic, Harry reads a newspaper article about a famous hero who ate this mysterious food called ambrosia.
