I make packaged gravy. DH grew up on it and doesn't like the homemade kind anymore. I don't mind, I am a pretty good cook. My aunt says "why re-invent the wheel?" McCormick makes perfectly good gravy I use the drippings from whatever cook to make it with though.
I'm sure there's something I am terrible at but I can't think right now. I know that sounds very conceited. Sorry ladies.
