When I stop to think about the collective resource that the readers of this column are, I am truly amazed. Among the thousands of readers, each with his or her own stash of cookbooks, recipes clipped and saved and networks of friends and family, there must be hundreds of thousands of recipes at our disposal. I am always grateful to those who share their recipes. In a recent column, I noted a few requests that went unfilled in 2004. In a matter of days, two copies of the following recipe for a Dolly Parton Salad made their way to my mailbox. One reader found it on the Internet another found it in an old F.O.E. auxiliary newsletter titled "Mrs. Eagle" so we're not sure of the recipe's origins, but it does make a tasty, Spring-like salad.
