I have a tea pot so I pour hot water into the teapot and just place the separate glass with the tea leaves into the pot and let it sit for 5 to 10 minutes. This of course depends on how strong of a taste and aroma you prefer.

If you do not have a tea pot just add hot water into a cup and some tea leaves into a tea strainer. Let this leaves sit in the water for 5 to 10 minutes.
