Step 1: A word for espresso machine adicts
Step 2: Ingridients
Ginger: You can use fresh or dried stuff. I prefer fresh ginger, as it gives a better taste (for this Instructable, I'm using pre-grounded ginger, which is a good compromise if you don't have access to fresh ginger root, or just too lazy to ground it by yourself)
Water: follow the machine user's handbook to choose the apropiate type of water for your beloved one.
Step 4: Dosing
Add the rest of the coffee, and tamp as usual.
