Attempting to bake custard-based fillings on flat pastry without creating a rim results in immediate overflow and burnt sugar pooling on the sheet pan. Forming a distinct, raised quarter-inch edge on each three-inch dough circle contains the liquid egg and corn syrup mixture while it sets. Maintaining medium-low heat during the stovetop reduction phase prevents the eggs from scrambling before the brown sugar fully dissolves into a pudding consistency. Line the baking sheet with parchment paper, as the bubbling corn syrup bonds permanently to bare metal upon reaching high oven temperatures.
Accurate temperature management dictates structural success here. Set the oven to 400 degrees Fahrenheit to trigger rapid steam generation in the pastry fat, creating flaky layers before the heavy filling weighs the base down. Monitor the cook time closely, removing the pan at the eight-minute mark when the filling jiggles slightly in the center. Residual heat on the wire cooling rack finishes the setting process.
