The Pumpkin Flour - Issues

At first, grinding up the dried pumpkin in the blender was going well. Then we heard and odd noise, and on dumping out the would-be pumpkin flour, we found
It's the little rubber washer that would normally be under the blade. Notice anything special?

That's right--we haven't found all of it. So I've been digging around in this

in order to find it. To be fair, I strongly suspect that there might have been a piece missing before I started this process, but we're trying to cut back on our rubber parts consumption.

In the meantime, nothing else really seems to be grinding the pumpkin. The food processor just flings it around & we're not really willing to try the coffee grinder. Coffee grinders aren't very tough & we've learned that using them for things they weren't really intended for is a good way to boost the coffee grinder industry.

So....unless we have any brilliant flashes of insight, which admittedly seems unlikely from someone who thinks of making pumpkin flour in the first place, the pumpkin flour will likely have to wait until we can find a new part for the blender...
