Place about 6 tea bags and 3 or 4 fresh sprigs of mint into a clean 2 quart glass container and fill with warm water. Cover. Place the container outside in the sun or anywhere the container will be exposed to plenty of sun for the next 5 or 6 hours. After the tea has steeped and reached its desired strength, refrigerate. You can leave the tea bags in for added flavor development, or remove them if desired, but do remove the mint leaves while storing. You may add a new sprig of mint or muddle some mint in the bottom of your glass when serving. Use within 2 to 3 days. Enjoy on a hot summer day!
