Start by washing the raspberries very well. Reserve
Put the water in a small pot on the fire. Add the raspberries and bring to a boil, and when it starts to boil, add the tea (in a filter, cloth or metal) and turn off the heat. Reserve with the lid on (without removing from the fire but turned off) and let stand for about 5 minutes.
After this time add the sugar or honey and the lemon juice.
Let it temper and, when it is no longer hot, keep it in the refrigerator until it is very cold. Serve with ice.
