I’ve edited my comment with some more recommendations. Mokapots are very forgiving, so you’ll be fine with preground coffee. If you get a decent hand grinder, I’ll bet money that you can’t tell the difference between that and any fancy grinder, Mokapots are just that forgiving.
Nice. Might try the freezing part. I’ve just been using a moka pot, nothing fancy.
