food, bev
My usual setup is to use a spice grinder (bleh) to get a finer grind with the aeropress also given by my sister, since she gave me a bunch of leftover paper filters and those are more tolerant of uneven grain sizes than meshes.
However, it takes a while for the kettle to boil when doing that, so I usually only do it when I'm cooking something for breakfast rather than going with something premade.
