I've been thinking about doing the same thing, but I want to automate it in such as a way that it knows what food is still unused in the house. Haven't found a solution for that yet, but maybe with smart fridges and/or image recognition we're not far off. Unless the hn crowd knows an existing solution.

You could try scanning the UPC codes and saving those in a database. I guess then you would have to scan them again to remove them which could be tedious. Maybe that idea will spark some inspiration though.
