Are you a serious coffee lover?
Here is my signature coffee recipe I make for myself every morning.
No high-tech necessary!
I have improved my recipe by NOT adding any sugar.
The key to flavorful coffee is selecting the "ESPRESSO" type of ground coffee. Even better, choose "organic" coffee.
Tip: I recommend making the coffee at the moment you plan to drink it, otherwise, coffee gets even more bitter after 2 hours. If you prefer your coffee black (no milk), just add more water before brewing.
