Is spectacular. Inspired by accounts (such as a recent story on NPR's The Splendid Table) of sun-tea alternatives, I made my own. It is perfect for Michigan summer, when the temperature is satanic and you can pick a handful of fresh mulberries to go with it; this method makes tea without bitterness. Take a teabag and drop it in a bottle of water, stick it in the fridge for a few hours or overnight, and you have a bottle of amazing. I've been experimenting with flavors, thanks to the local People's Food Co-op and By the Pound bulk foods store, which both carry ingredients as well as tea blends for cheap. I could use a tea ball, but I was given some marvelous fillable tea bags, and they do admirably.
Good flavors so far:
• Earl Grey
• Rooibos with lemon
• Lipton "red tea" (rooibos with strawberry and things)
Magic ingredient for black teas: sweetened condensed milk.
