What is forastera?

As an AI language model, I do not have any specific information about "forastera". However, "Forastera" could be a misspelling of "Forastero" which is a type of cocoa bean commonly used in chocolate production. Forastero beans are known for their strong, bitter flavor and are often used in blends with other cocoa beans. They are typically grown in West Africa, Brazil, and Ecuador.
