Blender, unscrew pitcher, screw base/blade onto a pint mason jar with dried peppers in it. The more, the finer. I will hold it all at an angle and let it slide and throw the powder(once you do it it will make sense). Take the jar off tap it to get the powder out of the base into the jar. Let rest a minute and open. I will pack with dried pods, powder, then open and pack again right on top. 2 or 3 times and then I will begin removing some before repacking.That's fine but I'm sure you still use good gear as the cheap coffee grinder I use for personal consumption wouldn't cut it and I'm sure I wouldn'tuseruin my Rancilio espresso grinder ...
You can also use bigger or smaller jars depending on your preference, as long as they are standard neck they should screw on.
Edit: Forgot to mention that they are already in a storage container when done if you want.
