What's a good spicy salt with only heat, and not a lot of flavor? I'm looking for something I can sprinkle on my food to add heat, but not change the flavor.  I typically add salt to just about everything I eat anyway, so I am considering a spicy salt, however, if there is some other spicy "powder", that would be perfect.  I have started using crushed red pepper flake, but it takes a fair amount to get the desired heat.  When I do that, the flavor is still normally fine, but the pepper flakes make the food gritty, and I can feel the dried bits as I chew... it ruins the texture of the food.  I've looked into pure capsaicin from an eye dropper, but that will be hard to spread over my wife's prepared dinners without adding too much heat.  Any idea's?
Try mixing up some salt and cayenne powder into an old spice shaker. That should make life easier. Start with a low amount of salt and adjust up to your level of heat.  If you end up putting it in a paprika container you may want to label it!
