Is there a good Free iphone app for downloading receipes and generate shopping list

Hi Friends

I want to organize the cooking and the shopping for the same. Have gotten so interested in cooking now.
I am looking for a free iPhone app that can help me organize/add recipes from my favourite sites and generate shopping list for the ones I select.

I found a few but not able to search from any site (sanjeevkapoor recipe) etc and add the recipe and have to search within their collection.

Please let me know if you are using something that would help with this.
Thanks
