When I learned about this concept, it blew me away! (I have no life..) Seriously, though, this is so clever. Instead of heating up a huge batch of water to make some ice tea, why not make a concentrated version of it that you just add to your water?! See, mind blown!
Heat up water to boil.
Add the tea bags, turn off heat, and let it sit for 10minutes.
Optional: Add honey or sugar
Store in container until ready to serve. Just add any amount (depending on how strong you wanted) to water and enjoy!
