Boil water in a kettle or pot, then pour it over the tea bag in a teapot or cup to steep.
Allow the tea to steep for about 3-5 minutes until it develops a rich aroma and a deep color.
While the tea steeping, pour your milk into a steaming pitcher and add vanilla bean seeds or a splash of vanilla extract, along with bergamot oil or extract.
Steam the milk using a frothing wand until it becomes creamy and velvety, with a light layer of froth on top. You should hear a gentle hissing sound and see the milk expand in volume.
Remove the steeped tea bag from the cup or teapot after 3-5 minutes, allowing the concentrated flavor to remain.
Add vanilla syrup or honey to the brewed tea, stirring well to combine and adjust sweetness.
Pour the steamed milk into the brewed tea slowly to create layers, letting the foam float on top for a creamy crown.
Gently spoon a little froth on the top to finish the latte, and optionally sprinkle with a bit of vanilla or citrus zest for garnish.
Enjoy your cozy London Fog tea latte, appreciating the layered aromas and smooth texture with each sip.
