If you use a cheap coffee grinder, run it for only ten to fifteen seconds at a time, then let it rest for a few minutes. (I get a decent result by grinding for nine seconds, waiting about two minutes, then nine seconds and I’m done.) By resting the grinder, you can make it last twenty years instead of one or two; you’re being kind to the metal in the motor that otherwise will overheat. You’re also being kind to the coffee, not heating it up too much in the grinding process.
Add a great flavor while you grind, it’ll taste fresh. I recommend cardamom seeds for starters (a common flavor around the Mediterranean and the Eastern Asia). Just toss in three or four whole seedpods; no need to shell the seeds. A dozen anise seeds tastes great, too.
