     We now think of chocolate as sweet, but once it was bitter. We think of it-as a candy, but once it was

a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it is an

ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over

chicken. The Mexicans also eat chocolate with spices like chili peppers.

     Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say

"Ugh!" and run away. Workers must first dry and then roast the beans. This removes the bitter taste.

     The word "chocolate" comes from a Mayan word. The Mayas were an ancient people who once lived

in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make

a drink.

     When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because

the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The

Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was

good for the digestion.

     In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste

of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block

of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste

of milk chocolate even better.

     Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie.

Favorite desserts are chocolate cream pie and of course an ice cream sundae with hot fudge sauce.
