Tastebook - create your own cookbook
This has been mentioned on a couple of blogs recently (101 Cookbooks and Apartment Therapy) and I think the concept is great. You have access to Epicurious' recipe collection as well as the ability to add your own and can put together a collection of 100 recipes for $35. This is a great housewarming, holiday, wedding or hostess gift. There are other services out there that do something similar, but I don't think any of them have the power of Epicurious behind them.
