3 1/4 cups ground coffee
8 cups boiling water
8 cups cold water
Ice cubes
1 can sweetened condensed milk
Put coffee grounds in large heat safe bowl. Add the boiling water and stir so all the grounds are mixed in. Let sit for at least 5 minutes.
Place a sieve lined with several layers of cheesecloth over another large bowl. Pour the coffee mixture through the sieve/cheesecloth straining out the grounds. Pour the coffee concentrate into a large pitcher and add the 8 cups of cold water. Refrigerate until cold.
To serve: Fill glass 3/4 full with ice. Add coffee and some sweetened condensed milk. I usually add about 1-2 tablespoons, but it depends how sweet you like it. Make sure to stir because the condensed milk tends to sink to the bottom. Enjoy!
Note: this coffee concentrate will keep in the refrigerator for up to a month. But let's be honest, it's not going to take that long to consume. :)
