Adjust your espresso grinder to a fine setting and grind coffee.
Using your recipe as a guide, measure an appropriate amount of ground coffee and add it to the portafilter.
Securely lock the portafilter into place and begin brewing the espresso.
While the espresso is being prepared, measure approximately 3 oz of milk.
Transfer the milk to the steaming pitcher and start steaming.
Continue steaming the milk until it reaches your desired temperature.
Once the espresso extraction is complete, transfer the two shots of espresso into the cortado glass.
Pour the warm milk into the espresso base. Make sure it’s equal parts milk and coffee.
Serve and enjoy your cortado!
