When I examined this one plant growing in mid-summer I thought I might know what it was. It was definitely a type of hibiscus, but which one? The Burmese gardeners were harvesting the leaves. I nibbled on the raw leaves and discovered it reminded me of the tea Flor de Jamaica that is common in Mexico and South Texas. The Burmese told me that they did not use the flowers. Recently the plants began to flower. I knew then that it was definitely the same plant. In fact, it is said to be the main ingredient in Red Zinger Tea. This is Hibiscus sabdariffa, roselle, rosella, Chaye-Torosh in Iran, karkade in Egypt, Saudi Arabia, and Sudan , Florida cranberry, Jamaica sorrel. and chin baung in Burma. (http://en.wikipedia.org/wiki/Roselle_%28plant%29)
I decided that I had to first look at the recipes that utilized the leaves. Chin baung kyaw is Burmese for Fried Roselle Leaves utilizing 2 bunches roselle leaves
shredded bamboo shoots (not raw), red chilli powder, turmeric powder, red onion, garlic cloves, green chilies and dried shrimp. Sounds delicious.

Finally the roselle plants started to flower, with a pale yellow flower and a red calyx. The red calyx is what is used to make tea in Mexico. The calyx is steeped or boil (depending on the recipe) and sugar is added. Ginger, cloves, cinnamon, and nutmeg are used in some areas to flavor the tea or agua fresca. The aqua fresca can be served hot or cold.
In Australia jam and jelly is made from the red calyxes. The seed pods contain pectin so one does not even have to add pectin. Lemon juice is also added.
