The daughter is trying to enjoy coffee. It's a peer pressure thing. It comes with good so I can't complain. The same peer is a vegetarian so my kid is expanding her list of possible vegetable options.
This recipe is for my memory.
5 ounces good coffee
6 quarts cold water
Combine them, mix, let steep overnight or at least 8 hours. Double strain through cheese cloth or I use the fine mesh insert from my drip coffee maker for the second straining.
Keep chilled and serve.
