The recipe calls for the use of some classic ingredients, but you can, of course, experiment and give it your twist if you want to.  If you want it to have a bit of a spice kick, add some crushed black peppercorns or dried árbol chiles- or both!  If you prefer the chili crisp having a bit of a bulky texture as opposed to it being a runny oil, add some crushed roasted peanuts into the mix.  Sesame seeds can also be a good addition to the chili crisp.
