I bought an espresso-maker at World Harvest the other day! I love this type of coffee pot because it is so simple and doesn't require any paper filters. It doesn't make Artisan-quality espresso, but it tastes like Madrid.
It has three pieces, the water goes in the bottom, coffee in the funnel cup (pack it in for a stronger cup!) and it all comes together in the piece w/ the spout.
You put all the pieces together and set it on the stove top. It takes very little time, depending on how high you turn up the burner. If you keep the heat low, it will taste less bitter and be much less likely to burn.
The water boils in the bottom half and is forced up through the coffee and then spills over the top, like a percolator.
Now I don't have to go through the embarrassment of ordering "a double decaf espresso with a little cold soy milk. Don't heat up the milk. Actually, would it be okay if I just added it?" like a true coffee snob. I am an ex-barista who OD'd on caffeine too many times to still enjoy real coffee. It is impossible for me to order like a normal person.
