Coffee-which is not coffee!
"CASCARA" from Spanish means "peel." It is the name (most commonly used worldwide) to identify the dried skin and pulp of the coffee cherry, that is, the fruit of the coffee cherry.
The coffee cherry is a fruit that is harvested when it is red. Before or after drying, depending on the process used, it is divided into its two main components: one side yields the beans, the other the pulp.
The beans, called coffee beans (which we all know), are roasted and then used to make the well-known coffee.
The pulp, called CASCARA (lesser known), is now mainly consumed in producing countries to make an infusion, like a tea. So it's more of a coffee substitute, rather than a coffee! A coffee substitute with caffeine!
The same name CASCARA is also used for the infusion itself, like e.g. Cascara tea or in english coffee husk tea.
