This tartlike version of pecan pie, a specialty of the South, is baked in a cake ring, available at baking-supply stores. A nine-inch springform pan will work just as well; just trim the edge of the dough to 1 1/2 inches all around.
To make cookies uniform in size, scoop rounded measuring tablespoons of meringue mixture onto parchment-lined baking sheets. Use your fingers to get all the meringue out
of the spoon (it is quite sticky). Don't bake on a humid day, or your meringues may not dry.
