Chocolate is an important part of Valentine's Day celebrations in many countries.
People often buy boxed chocolates and give them to a loved one.
In some areas, Valentine's Day is celebrated with chocolate festivals.
At one such event near Washington, D.C., the visitors tasted all kinds of chocolates and learned about the history of these sweet treats.
The tree grows these pods. You can feel what a pod feels like.
This chocolate festival also took place in McLean, Virginia.
Visitors started by learning about cocoa beans, the main substance used in chocolate.
Inside, you see the white color here is actually the pulp on the outside of the bean…
The visitors got to see how the beans are seperated from their husk, and then broken it into smaller pieces.
These cocoa nibs are ground on a heated stone, spices and other ingredients are added to produce a block of chocolate.
The festival goal was learn how chocolate was used mainly as a drink up to and through the 1880s, that was before the first candy bar was manufactured and sold.
David, a chocolate historian said, it is just a little too hard for us to eat like a candy bar.
So in Colonial chocolate making, they would have taken chocolate blocks in this form and grate it to make fine chocolate powder.
The chocolate particles are then mixed with hot water in a container.
We found an authentic colonial recipe, partnering with the folks at Colonial Williamsburg.
The recipe dates back to the 1750s.
And it is a recipe that actually documented nine different seasonings and spices in the recipe.
People who tasted the drink seemed pleasantly surprise.
Oh, it's delicious. It's very spicy and rich and not too sweet.
It's been great for the kids. They enjoy trying different chocolates and then learning about, you know, how their favorite treats are made. Very educational!
