Add 250ml of water into a small saucepan together with tea leaves.
Bring it to a boil and reduce the heat to medium low.
Add apinch of bicarbonate of soda. A pinch would equal about 1/6 of a levelledteaspoon. Add very little because the bicarbonate of soda may ruin the taste. Stir.
Simmer for 10 minutes and stir the tea occasionally.
Remove from the heat and add icy cold water.
Strain it into serving glass filled with ice.
Add milk into a small saucepan and turn on the heat to medium-low.
Immediately start frothing the milk with an electric whisk. Do not let it boil.
Milk will be ready when you have a layer of thick foam. This will take only a couple of minutes.
Pour it into glasses with tea and top up with froth.
