Backstory: Recently I've traveled a lot and I've been eating out at restaurants more than usual. When I'm in different places I like trying different types of food, not typical chains. This leads to some pretty interesting menu items and are often very tasty. I got to thinking, wouldn't it be great to create these recipes at home?

The Idea: A cook book that generates recipes based on the restaurants you visit.

Deep Dive: This app would tap into credit cards and analyze every restaurant a user has visited. To form the cookbook, the application would use recipes based off which types of cuisine's are visited the most and which items are common across those restaurants.

The app would suggest meals to make or partner with a food delivery service to sell ready to cook ingredients for the same meal. Users could also rate each recipe and the application would suggest new recipes based off that feedback.

Validation: After a quick search there doesn't appear to be anything like this out there. It's a unique variation on recipes and food delivery.

Monetization: As mentioned above, you could partner with meal delivery services. Another option to monetize would be to sell a printed cookbook of recipes for your users.
