I'm having trouble finding the right recipe/shopping list app for me. I would like something that allows the entry of my own recipes on my mac and can then sync them with my ipod touch. I would also like to have the ability to add either separate items or an entire recipe to a shopping list. Finally, I need to be able to access shopping lists offline within the app, as I have an ipod touch, so I do not have internet access at the store. Any ideas?
