The question here is about the following primitive method for making coffee. Having used this method for many years now I think it gives consistently good coffee, comparable to that from a good espresso machine but without the need for machinery or paper filters.
Recipe: Bring one cup's worth of water to a boil in a small pot. Add about a scoop and a half of ground decent-quality beans to the pot. Swirl gently until chalky bubbles appear. Filter through a tea strainer into a cup. Let stand briefly.
No need to grind the beans to a powder. The tea-strainer gets most of the grounds and the amount of sediment in the cup is about the same as in cafe espresso. The only electric component is a coffee grinder. Using pre-ground beans requires more coffee per cup, as some flavor will be missing.
In general this method produces coffee that is slightly weaker than espresso. While I might add a bit of sugar to espresso to counter bitterness if the beans are old or mediocre, the strainer method above gives coffee that is very drinkable without sugar.
It sometimes surprises me that this simple method isn't more widely used. Has anyone else tried it? Are there any drawbacks to this method? It isn't worth much commercially because it only makes decent coffee one cup at a time.
This method is adapted from one I saw used by fisherman in Brazil, except he used a sock instead of a tea strainer. Comments welcome.
