Coffee, 'strainer'

Not what the OP had in Mind,
I use one of these indoors all the time now as our water is so bad, especially when making tea! gets the big lumps of scale out. One filter paper lasts about 20 brews.

would think it pretty useful outdoors for coffee.

After the water comes to boil drop a splash of cold in the pot. Grounds sink to bottom of said pot.
