My parents still host Thanksgiving for our family, and my mom does the cooking. My mom is an OK cook most of the year, but Thanksgiving is her specialty. I have been nominated by my siblings to the be the family Thanksgiving host once our mother gets tired of it, so I know it's just a matter of time before I am brining turkeys and trying to settle on my own signature dressing recipe.
Since the turkey, dressing, potatoes, yams, and pumpkin pies (brought by my cousin, using our grandmother's recipe) are all already accounted for, my contribution is homemade cranberry sauce (an upgrade from years of canned cranberry sauce). To add some interest to it, I usually soak sliced dried apricots in orange juice the night before (instead of brandy, which may bother some of our Mormon relatives), and include them in the sauce along with some powdered ginger (although--bright idea I just had--this year I may bring some candied ginger home with me and try that instead). I've also tried to contribute various green vegetables in the past, but those are woefully neglected by the guests, so I've given up.
So, if you are not the main Turkey Day cook, what do you bring to the party?
