It may just so happen that this year (or every year for that matter) you were the oh-so-lucky individual "picked" to be the host of this year's holiday festivities...and you get to cook all the food, too.
So, you finally have narrowed down the guest list as to who is coming and who isn't (for the most part, anyhow). Now, you can move on to trying to calculate exactly how much Uncle Alfred can put away and if your 17 year old cousin will even eat at all...so how are you supposed to figure out how much to fix, then? You don't want leftover portions enough to sustain a small army for a week, but you also don't want dear old Uncle Alfred ransacking your cabinets for a little something more to satisfy him (after all, what if he found your chocolates? Oh, my!).
Don't lose heart, I have the perfect thing for you! Check out Cooking for a Crowd.
And by the way... I'd go ahead and hide those chocolates (just in case). Uncle Alfred may not like banana pudding. Who knew an old, fat bald guy could be so picky?
