Mix the water and milk and bring to a boil in a pan.
Add the teabags or tea and allow to steep till the tea is of desired strength.
In a cup, put the cocoa powder and sugar. Add a little of the brewed tea and mix well. Take care to avoid forming any lumps. Mix the cocoa paste with the rest of the brewed tea.
Allow the entire mixture to heat well and the flavours to blend. Do not over boil it. Serve hot.
