This custardy dessert features a flaky crust and a silky-smooth, sweet-tangy filling that practically melts on your tongue. Made with simple pantry staples, it bakes up with golden edges and a delicate custard center.
Let eggs and buttermilk sit at room temperature for about 30 minutes to prevent curdling. Cover loosely with plastic wrap and store in the fridge for up to four days, or freeze slices for up to one month.
