The noodle press works great. You end up with a dense puck and a melding of the flavors in the blend(s). It’s not a plug unless you started with whole leaf, but it’s dense.
The general process I use with the noodle press is to take the blend I want to press, microwave it for 5-10 seconds, and load the press. Microwaving makes the leaf more pliable and releases some moisture.
Crank it down and re-tighten later in the day. Just give it a crank if it needs it when you walk by the press. After a few days it’ll have stabilized. Leave it in the press for about 10 days before releasing it. You could add gum Arabic if you want a really dense puck but I’ve never bothered.
Adjust the process as needed for you.
