can you tell me about how much it produces per minute? I want to make
a lot of poppyseed torte so it should be finely ground but not take all
day to grind ~1000g worth

I'm toying with the idea of getting an electric mill - not only for
poppy seeds - something more all-purpose like this

any thoughts on whether it really is suitable for poppy seeds?
