First, boil water in a tea kettle or a separate pan.
Fill the moka pot basket to the top with espresso grind coffee, but don't push it down, simply gently smooth the top out so it's flat. Set aside.
Once your water is boiling, fill the bottom of your moka pot until the water reaches the bottom of the metal valve/bolt.
Place the coffee basket on top of the hot water-filled bottom and carefully strew the top onto the bottom. Make sure it's on tightly.
Place the whole moka pot on med-high heat.
Leave to brew, covered, until you hear sputtering. Open the top and you should see foamy bubbles coming out the top.
Quickly remove the moka pot, run the bottom under cold water (to stop the cooking and keep your espresso from getting bitter) and use as desired.
