Measure 1 cup of coffee grounds into a quart size mason jar
Cover the coffee grounds with cold water.
Shake the jar so all of the grounds are saturated.
When the coffee grounds settle top off the jar with more water.
Allow to steep for 24 hours.
Strain Coffee Grounds
Place a plastic fine mesh strainer over a bowl. Line the strainer with a coffee filter.
Pour half of the jar contents into the strainer. Allow all the liquid to drain.
Pour the remaining coffee concentrate and grounds into the strainer. Allow to drain completely.
Swish about a ¼ of a cup of water in the jar to get the last bits of coffee grounds out of the jar. Pour into the strainer.
Press the grounds with the back of a spoon to push all the liquid out of the coffee grounds.
Wash and rinse the jar.
Pour the coffee concentrate back into the clean jar.
Keep refrigerated until ready to make a glass of cold brewed iced coffee.

Recipe Expert Tips
I first learned of the cold brew method of iced coffee from the Pioneer Woman's blog. She makes a much larger amount of cold brewed coffee concentrate. I've adjusted her directions for my own use making a smaller amount of coffee concentrate that lasts me about a week.
