Being a foodie with the iPad should come naturally. And with panache. So you can look to Yummrs as a way of nurturing your palette in a way that's great for you and for the party you're throwing.
Yummrs connects to your favorite cooking blogs, and manages them by presenting the delicious foods you'll want to make front and center. You can organize the recipes you like into an infinite number of recipe books that you can access with just a tap. After all that, you can then share those recipes with friends via Facebook, Twitter, and Yummrs' own social network.
I'd personally start with a dessert recipe book. [iTunes via Yummrs]
