My husband got an iPhone for Christmas and he's been opening presents in the form of applications ever since.
No slouch himself in the cooking department, he loves to find new recipes to try when it's his turn in the kitchen.
Lo and behold, he discovered the epicurious.com app for his iPhone that not only let's him browse recipes, but when he finds one he likes, it gives him a shopping list and also allows him to e-mail the recipe to share with others.
I did some surfing on the web and found that there are lots of different recipe apps available for no charge for the iPhone and other similar phones with online browsing.
You can check out epicurious and other apps at the iTunes store, or check out a review of the 10 best here.
