I just put about a teaspoon of either fresh or dried tea leaves per (6 oz.) cup of tea, cover with boiling water and let steep until it is as strong as I feel like having it (usually 3 to 10 minutes). Strain into a cup and add sugar, honey, lemon, cream, or whatever you like in it (I like just sugar or honey).
If you want iced mint tea, let steep 10 minutes, strain into a pitcher, and add sweetening, if desired. Cool or chill and serve over ice.
