In which country is hibiscus tea considered to be the national drink?

Hibiscus tea is a herbal tea made as an infusion from crimson or deep magenta-colored calyces (sepals) of the roselle ('Hibiscus sabdariffa') flower. It is consumed both hot and cold. It has a tart, cranberry-like flavor.

In Africa, especially the Sahel, hibiscus tea is commonly sold on the street and the dried flowers can be found in every market. Variations on the drink are popular in West Africa and parts of Central Africa. In Senegal, bissap is known as the "national drink of Senegal". Hibiscus tea is often flavored with mint or ginger in West Africa. In Ghana, it is known as "sobolo".
