IEGEL: Christine Carroll recommends a free app with a long name: Chow Thanksgiving Dinner Coach. Basically it lays out your meal for you.

CARROLL: It starts with roasted turkey. It covers gravy, mashed potatoes, green beans. So really, its nine recipes and you're done - that's your menu.

CORNISH: If you're looking for more advanced culinary inspiration, Carroll suggests this app: Holiday Recipes and Party Planning Guide from the online cooking site Food 52.

"Chow Thanksgiving Dinner Coach" sounds like a great app for one holiday.

But "Holiday Recipes and Party Planning Guide" sounds useful for multiple holidays... 

I just downloaded the free iPhone version of How to Cook Everything and am impressed with the techniques section. Illustrated clear instructions on everything julienning to roasting.
