Place water in a tea kettle and bring to a boil.
Turn the burner off.
Remove the lid of the tea kettle and drop in the tea bag; cover and let stand 5 to 8 minutes.
In the meantime, place milk in a heat-resistant mug and stir in the brown sugar and vanilla.
Heat up the milk in the microwave for about 1 minute, or until hot. DO NOT BOIL. Watch it very closely. You can also heat up the milk in a saucepan set over medium-high heat. I use my glass measuring cups for this part and just heat up the milk in the microwave.
Remove milk from heat or from the microwave.
To froth the milk you will need a milk-frother OR you can use a French Press.
Using a frother, froth the milk for two minutes, or until frothy. To use a French Press, add the milk to the French Press and pump the plunger until milk is doubled and frothy.
Pour the hot tea in 2 heat-resistant glass mugs.
Slowly pour in the milk, holding back the froth with a long spoon; then, spoon the froth on top.
Optional: Garnish with dried lavender flowers or earl gray dry tea leaves. (open up a tea bag and sprinkle some of the tea leaves on top of the tea)
