Crust Protection: Because of the longer bake time, wrap foil around the crust edges for the first 30–40 minutes. This prevents overbrowning.
Fat Content: Full-fat buttermilk creates the creamiest result. Reduced-fat options are fine, but the texture may be slightly lighter.
Storage: Wrap leftovers or store in an airtight container in the fridge for up to 4 days.
