In the Google documentary on ARTE somebody told a story about how his grandmother discovered Google: she typed ingredients she would like to eat in the search bar and Google returned recipes for dishes with exactly those food combinations. Today, thinking about lunch, I tried the same and it worked very well.
Wouldn’t that be a nice fridge feature?
Based on the food what’s left, the fridge looks up and suggests recipes. Nowadays one could extend it even with some community features. Like last.fm tracks the music users play on iTunes, the fridge robot scans the food in the fridge and recommends recipes, based on profiles of other users with similar fridge content and taste.
