Going to the web for a new, untried recipe is very hit-or-miss. I think it's more useful if you've already made something similar.<p>If I try something new I usually go to two or three standard sources, e.g. Joy of Cooking, Cook's Illustrated, Silver Palate or Dr. Oetker and then compare with a handful of search results from the web. That way I get a feel what the range of each of the ingredients is.<p>What would be really interesting to me is an app that pulls down as many recipe sources as possible, normalizes the ingredients and displays them all on a percentage scale. Doesn't really help with learning a new recipe but that would be great for experienced cooks looking for specific variations.
