What sicman said. I just made my 1st powder last week (fatalii/peach ghost scorp mix), and got lazy halfway through deseeding the peppers so left the seeds in the rest. By the time they were fully dried nearly all the seeds had fallen out. The few that were left in went in the grinder as well. Didn't notice any bitterness at all, just all flavour up front then a rush of heat.Â
