Children and curious adults interested in the origins of everyday foods like chocolate.
Chocolate comes in many forms, from chips and coins to liquid fountains.
Miuri asks Doug where chocolate originates from, sparking the video's main topic.
Chocolate was first known only to people in Central America, who discovered its source.
Chocolate comes from cacao trees, which have colorful, football-shaped fruits on their trunks.
Inside the fruit are slimy pulp and brown seeds, which are fermented, dried, and ground.
The Aztecs made a bitter drink called 'choco-aro' from the seeds, the origin of our word 'chocolate'.
Sugar was added later, making chocolate sweet and leading to its global popularity and solid forms.
