In a pot, combine tea leaves, 5 cups water, and baking soda. Bring to a boil.
Simmer and keep boiling till almost all of the water is evaporated and only a cup or so remains, this will take about half an hour. Once it is reduced, add more water to make it its original volume and boil it again till half of it is evaporated.
Top for the third time with cold water to make it its original volume. Put back on the heat and keep mixing it with a ladle, frothing it till it gets a good boil. Then take it off heat. It should look dark red in color because of the chemical reaction between the baking soda and chlorophyll in the tea leaves. Either us right away or cool and store in the fridge to heat and make a cup of tea later.
