What you do is get a quart jar, add 1 cup of ground coffee, fill it up with water, shake, then set it on the counter 12-15 hours. The next day strain it twice. I use a small strainer the first time then put a coffee filter in the next time. Then use about 1/4 cup of this concentrate, add milk or flavored creamer, if you need sugar you will need to use sugar water or sweet & low so it will dissolve. If you want hot coffee just add boiling water to the concentrate instead.
