You will need a teapot, water, mug, mint tea bag, sugar, and a spoon.

To begin, fill a teapot with water, you want enough to fill a mug a little more than halfway. You want to leave room for other fix-ins like sugar, and you don't want to be at risk of splashing yourself with the hot water. 

Once your teapot is filled, close the lid and place it on the stove. Then, turn the dial on the stove to medium (or about halfway). While the water is boiling, you can pick out a mint tea packet. Remove the tea bag from it's packaging and place the tea bag in a mug. 

When the water is boiling, you will either see an aggressive steam come out of the spout of the teapot or you will hear the pot whistling. Once either of those happens, you can turn the heat off and carefully grab the teapot. Slowly pour the hot water into the mug as to not cause any splashes. You can stop pouring when the teapot is empty of any water. Let the tea bag steep in the hot water for a few minutes; steeping is when the flavor of the mint tea in the tea bag is diluted into the cup of water, waiting a few minutes ensures that you're getting a deeper more concentrated mint flavor. 

As the tea steeps, grab a spoon and a container of sugar. Add any amount of sugar you'd like at this point into the mug with the tea, I add about three heaping spoonfuls of sugar because I prefer my tea on the sweeter side. You're free to add as much sugar or as little sugar as you'd like. If you added sugar, take your spoon and stir the sugar and tea (slowly but deliberately) to dissolve the sugar. Once you can no longer see any sugar granules, you can stop stirring as this means the sugar has dissolved and is now evenly distributed throughout the tea. 

At this point the tea has cooled down a bit and is now ready to drink!

The mastery for this lesson would be someone being able to make a cup of mint tea accurate to the written and instructed lesson. To properly instruct this lesson I would ideally be making a cup of tea as I go through the different sections as an example.
