The simplest way to make (good) coffee...

...is with a pour-over. Among my various coffee makers is a vintage (c.1950s?) Melitta 101 3-hole cup-top "Kaffeefilter" in white ceramic.

Since size 101 filters are next to impossible to find here in the States, I use Melitta's #2 brown cone filters, and fold the side seam twice instead of just once. This gives the filter the correct diameter (or close enough, anyway). I wet the filter down with hot water to wash away any loose fibers, and to pre-heat it. Add two (7 gram) scoops medium-fine ground coffee, and slowly pour 10 ounces of water (just under boil), slightly stirring to keep the grounds good and saturated. Brews in about 3 1/2 minutes.
