Don't discount instant pudding: We've got an outstanding recipe for cinnamon rolls that adds instant vanilla pudding to the dough. Adds eggs and milk without adding more liquid.
But on topic: when it's time to cook something I haven't done before, I'll scour my cookbooks (see the favorite cookbook thread), leaning toward Joy (unless it's ethnic, which it often is), and the two Gourmet books, perhaps a celeb chef or two. A search of the intarweb doesn't hurt, although the ability to find a decent recipe out there can be tough.
I don't go so far as the
Mean Chocolate Chip Cookie approach, but I have been known to average or combine a couple of recipes. Generally the less potchke-ing done to the ingredients (not necessarily the simplest recipe), the more likely it's authentic (unless it's French) and going to taste good. Cook's Illustrated does way too much potchke-ing, but at least when you read their articles, you know *why* they're fussing, and when you can de-fuss the recipe, and what will happen if you do.
