Step 1: You will need
- 180 ml water
- 25 g coffee
- 1 espresso percolator
- 1 teaspoon
Step 2: Prepare percolator
Unscrew the base of the percolator and remove the lower filter. The base has water marks inside that guide you as to how much should be poured in.
There are several different sizes of percolator on the market - the one we're using here is a small 3-cup measure.
Once the water's poured in, put the filter back in place and spoon in the coffee. About 3-4 heaped tea spoonfuls will do it, until it's full to the brim.
Now screw the top half back on, making sure it's tightly secured.
Step 3: Switch on stove
A small ring will do, especially if you're using gas - don't let the flames go beyond the base of the percolator. Now leave it for 3-4 minutes until it gets to the boiling stage, at which point percolation begins.
By now your espresso is well on its way. Water has boiled its way up the spout of the lower filter and forced itself through the coffee crammed on top. The water and coffee mix then passes through a second filter and up another spout to reach the top part of the kettle.
You'll know it's done when the distinctive percolating sound stops. Now you know all the water from the bottom has gone to the top, and you can turn off the stove.
Step 4: Serve
Pour the percolated espresso into a small cup and add sugar if you so desire.
