Like you said CPW, remove any debris, and cut you a small piece of parchment  paper . Take the pollen and put it in the parchment paper, then fold it up like grams of coke you used to buy...he,he,he. Then take that and put it in a air tight container, like a instant coffee container with a screw on lid, and put it in the freezer. As a added option you can also put a dessicant in with the pollen but that's not totally necessary. I've stored pollen like this that lasted for years. Peace and Happy New Year
