We could write integration for epicurious, allrecipes, and other sites that offer ingredient lists for the dishes they displate. We could also write it to integrate with food network. This thing can hook up with the manufacturer/grower’s site that has nutritional information in a database. We’ll pull all of that in and you can have your shopping list, and hover over each item for all of the information you could ever want on an item… including google shopper prices, it can hook up with your GPS coords and let you know the cheapest place to find the ingredients within <user defined> miles.

All of this built in to a concise shopping list that you have access to from virtually anywhere in world.
