Combine in a pitcher and stir:
1/2 lb coarse ground coffee (I like Stumptown's "Hair Bender" blend)
4.5 C filtered water
Cover with lid or plastic wrap and let it sit at room temp for 12 hours. Then filter the coffee and keep in the fridge. I found it tasted best when I filtered with a mesh strainer-- using a paper filter seems to get rid of too much and make the coffee taste like drip coffee (eww).
Mix the coffee concentrate 1 part coffee to 2 parts water/milk and 1 part ice; or 1 part cofee and 3 parts hot water/milk.
Update 5/7/2010: this stuff is really delicious. I can scoop out 1 TB of coffee concentrate and add 3 TB of rice milk and I'm all set. I also tried it with hot water and some cream and it was really good that way too. You'd better measure this stuff though since it is VERY strong and I was using way too much coffee just pouring by eye.
I really like this recipe/method because:
- it didn't take any special equipment (I don't have a cofffee maker or espresso maker or any of that)
- do-ahead and freezes well- next time I would freeze into individual portions using an ice tray. This will be great to have on hand when coffee-loving relatives or guests come over
- tastes as good as the real thing from the coffee shop- just make sure to use distilled water and good/fresh beans- but way cheaper
