My Mom was a pretty good cook, but her Mom was Italian, so most meals were pasta, lasagna, etc. So she never really made gravy, just a packet and add milk. Then one year, (if you can follow this, lol) my Dad's best friend's Mom & Dad came and she taught my Mom how to make gravy with the pan drippings (no, it's not really hard, but it's nice to have some direction about the proportions).
It's just DH & me for Thanksgiving (we don't live local to our parents, or family) so what I make is dependent on how much work I want to put in for 2 people, and 15 min of eating. So some years it's a jar, some years is homemade. This year is the first holiday after losing my Mom, my brain/body is still too fried so when I saw the Turkey gravy at Trader Joe's, I picked it right up. We're also just getting a store bought pie (but from a local place), picking up rolls from a bakery, and I just got a turkey breast instead of a small whole turkey.
