I always follow the Toddy directions you can see here, but this time added an extra cup of water. If you don't have a Toddy you can brew the coffee, water and chicory in a covered pot for 12 hours. Then strain through a sieve to remove the ground the coffee.
I also poured some of the coffee into large ice cube trays and made coffee cubes!! This makes your iced coffee extra strong and not watered down!
