First, you mix the grounds with the water (I use 12oz med. ground coffee, and 8 cups of cold water.)
Then you let it sit overnight. Then you strain it, and are left with a wonderful coffee concentrate.
Then you mix it with hot water for hot coffee, or- as I've been doing- with ice and soy milk, for a delicious iced coffee. It is sooooo smooth and delicious! Yum!
