MollyB - you can use the Report an Error link at the bottom or the Contact link at the top. They both go to same place - me! Unfortunately sites do change the URLs of their recipes (without doing redirects, which would be so helpful) or they delete recipes completely. The latter situation is what has happened at Serious Eats which has changed owners a couple of times in the last few years and the latest owners seem to have decided to delete a lot of the recipes. The Kitchn changed the URLs on some recipes and we correct them whenever a member informs us of a broken link. I have now fixed the one you referenced.
