Heat your water in a kettle or on the stove. For best results you want the temperature to be about 175°F. Do not pour boiling water over your tea bag or it will burn your tea.
Steep 1 cup (8 oz) of green tea according to the package directions in a wide mug. Typical steeping time for green tea is about 3 minutes.
After three minutes is up, take out your tea bag and squeeze any excess tea out.
Mix in 1 teaspoon (or less if you prefer less sweet) honey until fully dissolved and incorporated into the cup.
Froth 1/2 cup of whole milk (not hot milk, but warm!) using a milk frother, or immersion blender.
Pour the frothed milk over your tea and enjoy!
Notes
If you prefer an iced green tea latte, before adding the milk, pour your tea over a tall glass full of ice. Follow up with the milk, but this time don't heat it before frothing, and enjoy.
You don't need fancy barista skills or an espresso machine to froth milk, nor do you have to have a handheld milk frother. To make cold foam without a milk frother, just pour your desired amount of milk in a mason jar or other receptacle, and use an immersion blender to make it foamy. While on low speed, move the blender up and down for about 30 seconds, adding as much air to the milk as you like to get it nice and fluffy. If you don't have an immersion blender, you can do this in a regular blender, too.
Add a tiny splash of vanilla extract for a fun spin!
