I've searched around and I don't think I've seen a thread like this, if there is one, my apologies.
how big a turkey for 10 people
Ir probably won't surprise you that someone has created an on-line Turky Calculator. This tells us that for 10 people--six adults and four kids--let's say with normal appetites and no leftovers (They thought of everything.) you would need . . . 8 punds of turney, 6 cups of stuffing and 16 ounces of grave.
