It is one thing to go out for tea or coffee but pre-made cold brewed coffee is something that I find extraordinarily expensive at the supermarket, especially as it so easy to make your own.
Make this instead! Iced Coffee Concentrate
Grind one cups of coffee beans coarsely, add the ground coffee to 2 cups of water that has been left to come to room temperature using a French press, large jug or jar. Leave covered on the countertop for 24 hours. Push down the press or if using jug/jar strain through a filter or cheesecloth.
To serve: Fill a glass with ice (you can make ice cubes from the cold brew if you do not want the coffee diluted) Add your coffee concentrate, milk, water, soy, almond, cashew, coconut or sweetened condensed milk in whatever proportions you like. All are delicious. Try starting with half of each. If you take sugar, make a batch of simple sugar syrup to use with your cold drinks. If you want to make a larger batch, just double the amounts.
