I have wanted to build something like this for consuming news sites, especially when my ad blocker has to be disabled. But thinking more long term ... what about a ML project that can look at many recipes and do a kind of PCA, figure out the essence of a pound cake for example and use actual data to show the main variations as clusters in a high dimensional state space. Or even try to reduce Thai or Mexican cooking to certain prototypical dishes and have versions at different skill levels for the aspiring home chef.
