You know, I, too, am very particular about my Thanksgiving menu. Growing up in a secular Jewish household in which we didn't celebrate any Christian OR Jewish holidays with big meals, Thanksgiving was a huge deal. My menu is ritual in and of itself, and even though I'm religious now and DO celebrate those Jewish holidays, I still go to more trouble on Thanksgiving than for any other holiday, except maybe Passover.
Which is why I cook everything myself and don't let anyone bring anything except flowers. Period.
Bottom line, if you want it done your way, do it yourself, and if you don't want to do it yourself, accept that it won't be done your way.
