it's almost impossible to find any decent poppy seeds where I live
I live in fucking
Indiana and there are a fuck-ton of them. You just need to look harder.
PS mcormick doesn't work, you want sort of 'off brands', there is one here called 'spice time' and there was a really strong brand at martins grocery store called, if I remember correctly, 'spice trader'. I would tell you to check smaller stores and especially 'country store/feed store' type places, but I am not sure if you have the transportation to run all over town looking for this stuff. It is probably for the best anyway, as I am sure you will just get heavily addicted to them and your life will become a nightmare.
edit - after reminiscing for a bit, I realized that 'spice trader' is the brand that Marsh grocery store carries. Those work too, but the strong ones I mentioned were something with 'spice' in the title, like 'spice cupboard' or something.
