Not sure if you do this, I add the chili powder to the meat as its cooking and when it is almost done I then add red hot to it. For me it doesn't make it to hot doing it this way.
Maybe I started doing this because I buy the cheap stuff. Last time I bought McCormicks Mexican chili powder thinking it would be better but I don't think so.
Maybe you should score and just drop a jelopeno pepper in when cooking, scoring will give flavor without making it too hot
