Does your espresso ever come out bitter and burnt? May I suggest a different way to make your Italian Joe: cold brew espresso. Cold brew espresso does not need any special equipment. More time consuming, yes, but with a little planning it takes no effort and is worth the wait!
Place both ingredients in a glass jar. Stir or shake to combine.
Place jar in the refrigerator for 18 hours. Tip: set an alarm or calendar reminder on your phone so you don't forget
When ready, pour mixture through a coffee filter to strain. Your espresso is ready to drink straight, be made into a espresso drink, or refrigerated for later use. Yield is about 2.5 oz., or about a shot and a half of espresso.
