Carol Sue Ravenel, who submitted this recipe, told us that she found an almost identical one on the Internet, suggesting it probably originated in an old Jell-O cookbook — undoubtedly a popular recipe source for her aunt and other women of her generation. That recipe suggested strawberry- or lemon-flavored gelatin rather than her aunt’s preferred flavor of raspberry. We have to confess we were extremely skeptical how any Jell-O variety would pair with tomatoes, but all of us who tried it found it oddly appealing. The tomatoes give it a fresh taste, and the blue cheese dressing provides a nice, creamy contrast to the sweetness. So go ahead — serve it to guests. Just keep the “surprise” to yourself.
