This is a consistently excellent resource, and I love the many small, essential bits of polish they've applied to their iOS app, like preventing your iPhone's screen from turning off when you're reading a recipe.

Something I'm surprised I haven't seen mentioned is Serious Eats. J Kenji Lopez-Alt does some absolutely excellent recipes (hello Halal Cart Chicken & Rice).
Serious Eats is good too.
I used to use Epicurious quite a bit back when they were a pretty early-on serious website for recipes. But with the demise of Gourmet and other sites like the NYT upping their game, I don't consider them top-tier any longer.
(Though, speaking of reuse, Kimball basically went and made an almost clone of CI that IMO was obnoxiously clode to a direct copy.)
One thing I'm looking forward to adding is tagging recipe steps as do-ahead, mis en place, early, late, and last minute. This will make it a bit easier to think through the mental gantt chart I use when cooking a dinner composed of a bunch of dishes. Also a simple scraping utility for importing.
The thing all these have in common is that they're reactions against the festering cesspool of hostile-UI, low-information-density, pages full of affiliate links that are today's cooking sites. (NYT cooking very much excepted.)
I wish we had a better mechanism for including more people in the project of iteratively refining the way we think about life tasks and improving the tools we use to think with. I think this is a great conversation and wish more people who like to cook could participate.
