I use it as a regular chile powder for things like plain old American or Mexican chilli con carne. Pretty much anything you make that calls for a semi hot pepper powder.
If you want to get creative you can use it to make a “kimchi themed” hot sauce. Most hot sauce is not much more than chile peppers, salt and vinegar. Add some kimchi to the mix and blend it well. The Kimchi by itself wont be hot enough to make a sauce but by adding hot fine pepper powder it works. Ive done it and the kimchi hot sauce is really good on noodles.
