Few years ago had the opportunity to work in Mexico and tasted the Agua de Jamaica which always fascinated me for the deep crimson color and the fabulous taste. It is a refreshing tea, with the proper balance of acidity. In Mexico it is served cold with sugar and a drop of lime juice. Later I found this tea in Singapore, where it is called Roselle and have enjoyed hot, the form which I prefer. Found the same tea in Cairo, where is called karkade and is sold on the streets competing with the black tea.
The Hibiscus calyxes can be used alone or in mixtures in many herbal teas.
