I originally got the idea for tea infused vodka here (the grand prize winner at the bottom). The instructions can fit in a Twitter message with room to spare: tea bags in vodka for 3-5 hours.
After a few hours, the vodka darkens, and its ready to drink! Mixed with lemonade and seltzer, you get a Arnold Palmer like drink with alcohol (a John Daly?) or a cherry lemonade. Both are so delicious that they're dangerous, because you can chug them down on a hot summer day.
