How to Make It
Brew a strong half-cup of tea with the tea and the hot water while you heat the milk in a smallish saucepan over medium heat until small bubbles begin to form around the pot’s edges.
Whisk in the vanilla and, if you like, honey, then whisk aggressively, until the milk is very frothy. (If you have a frothing wand or fancy milk-steaming machine, you could use that instead, but a whisk gets the job done admirably.)
Remove the tea bag from your mug and pour in the milk, holding back the foam with a spoon until all the liquid is in the mug, then spooning it over the top.
