Disassemble your stove top espresso pot (mine says it is a six cup or oz. pot)

Fill water into the bottom chamber of the pot to just below the release valve

Fill the filter with the espresso grounds to the brim, but do not tamp or pack down (the steam won't be able to pass through to make the coffee)

Reassemble the pot making sure all seals are tight

Place the pot over a burner on the stove the is set to medium-low heat.

In a glass bowl with a pour spout (like a liquid measuring cup) add the sugar to the bowl

Once you have the first Tablespoon of coffee in the pot, pour it over the sugar and return the pot to the stove for the rest of the coffee to brew.

Using a spoon, whip together the sugar and coffee furiously for 2-3 minutes until you have a tannish brown foam start.

Once the pot finishes brewing, add the whole pot to the bowl with the sugar mix and start beating again until you have a nice layer of a tannish brown foam at the top (the espuma)

Pour carefully into two demitasse cups so as to preserve the foam top on each cup and serve immediately.
