Tools that you need are AeroPress or similar, tablespoon and grinder
Stack your AeroPress.
Place a filter inside the drain cap—if you can use more than one to slow the flow of water when pressing.
Lightly rinse the filter and place the drain cap and filter inside the compartment of the press. Place the press on a stable cup or mug.
Prepare about 2 tablespoons of coffee by grinding the beans to a fine, table salt-like consistency.
Drop them into the filter. Note that adding more coffee than normal during these makeshift brewing sessions might work in your favor — it will create a more reliably concentrated shot.
Add approximately 3.5 fluid ounces of water, heated to about 200 degrees. Stir with the coffee. Then, press down on the plunger—hard. Remember, espresso depends on the pressure! Transfer your espresso (or coffee shot) into a demitasse and enjoy it!
