If they are already hulless why would you have to press or crush them? I found the link below that details how to roast hulless seeds. Hope it helps.

My guess is to press for oil. I have considered many options for similar oil crops, but haven't come up with a feasible solution. I sometimes find oil presses/expellers for home use, but not enough info to justify buying one.

Yes, it would be to press for oil, sorry I wasn't clear on that in the first post. Shouldn't try to type a coherent post when I'm falling asleep at the keyboard. LOL!

Yum! We were in Styria last fall and enjoyed this oil in many of the local specialties: soups, salads, pasta, etc. I brought back a small can and have been using it like the precious commodity that it is.
The processing appears to be more than just pressing the raw seeds. I found a link which has a somewhat abbreviated description of the processing method, but it's a PDF file and I cannot seem to attach it to this message. If you "google" the terms "Steirisches Kürbiskernöl processing" it should be the first PDF result that comes up and look like this:

Good luck!
