shekinahcancook, 
Not sure this will work with gluten free substitutions, but I'm thinking about trying it. Has anybody else tried it?
We do have a small spice/coffee grinder, so that should be ok.
I'm presuming the 7 ounces of finely ground poppy seed is the AFTER grinding amount, as this seems to be the bulk of the "flour" in this recipe.
Also says to keep refrigerated, which might mean it's structurally unstable to begin with, and using gluten free flour will make that worse...
i guess worst case scenario, we'll serve it in a bowl like spoon bread and drizzle chocolate on top.
