The one I'm thinking of was a basic, yet slick affair, with boxes that you ticked if you had those ingredients in your larder, all categorised under various sections.
I'm pretty sure it was American, or that way inclined, but had a very decent range of recipes and didn't steer you down the usual predictable paths for meal choices.
I guess it could have changed its interface over the years, but none of the ones posted so far have clicked with me.
