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!
Sprinkling powders or flakes made from hotter types of dried chili pepper (which you need to use if you dont want the end result tasting of paprika) directly over food will end up giving you a rather harsh type of heat.
Consider using a chili-infused oil, or actually cooking a finer ground dried chili in oil for a moment before adding the mixture to the food (be careful with the fumes). Capsaicin is oil soluble and tastes much better to most people if solute in oil.
Be careful experimenting with pure capsaicin (or >>100000 scoville peppers or preparations), it is actually considered a hazardous substance for a reason.
There are plenty of hot sauces that really don't taste like much but heat. That won't really have a noticeable texture at all, unless you're putting it on something dry.
Or, you can just get a hot chili powder and either use it by itself or mix it with salt. You might not want it too hot, since it's hard to sprinkle perfectly evenly, but in any case you can find a level of heat that works for you. You could also mix it with salt yourself if you like the spicy salt idea, and find a good ratio of salt and heat. Cayenne is probably the most common in the US, but there are plenty of other peppers out there, especially if you start looking at Indian stores.
