Fill a glass, bottle, mason jar, pitcher, or carafe with ice, fruit, and herbs. Fill to top with water.
The water will start to take on flavor after about 15 minutes, but wait 30-60 minutes for best results. Refill with more water and ice until fruit flavor is gone.
Notes
Citrus fruit will turn the water bitter in about 4 hours, so drink any citrus-containing flavors before then.
