Get a cheap/used popcorn popper (metal chamber, not plastic). Pour in a cup of green (unroasted) coffee beans. Start popper. After a few minutes, you'll hear the beans crack (you'll know). Keep roasting. The moment you hear a second round of cracking start, dump the beans into a large cool metal pan, swirling and transferring to another cool pan often until about room temp.

Store beans in sealed container for 0 minutes to 1 week (flavor changes over time).

Grind with burr grinder to fine.

Brew thru AeroPress.

Don't drink coffee because it's a cultural obligation (per poster above). Drink coffee because, done right, it's awesome.
