Digital Mulligan Stew

Your fridge contains onions, lemons, and some pork; the pantry holds flour and baked beans. This is dinner? You bet. Head over to Cooking By Numbers, check off what you have from the site's list of 50 staples, and voila;--relevant recipes appear, rated 100 percent (if you have all the ingredients) or a lesser percentage (if you lack a few). While gourmet cooks may find the pickings slim, the site is perfect for the desperate parent or the forgets-to-shop bachelor. A great companion site: the Cook's Thesaurus, which has the scoop on any ingredient--how it's eaten and prepared, how to tell when it's no longer fresh, alternative names, and acceptable substitutes.
