To revive a day-old sourdough loaf, lightly dampen the crust under running water and then bake it in a preheated oven at 350°F (175°C) for 5-10 minutes, or until the crust is crisp again. This will rehydrate the crust and restore some of its original texture.
Day-old sourdough often loses its appealing crust and becomes somewhat hard due to moisture loss. The goal of reviving it is to reintroduce moisture to the crust and warm the interior, making it palatable again. Here's a step-by-step guide:
Preheat your oven: Preheat your oven to 350°F (175°C). This temperature is ideal for re-crisping the crust without over-baking the bread.
Dampen the crust: Briefly run the sourdough loaf under a faucet, lightly wetting the entire crust. You don't want it soaking wet, just damp. Alternatively, you can use a spray bottle to lightly mist the crust with water.
Bake the loaf: Place the dampened loaf directly on the oven rack. Baking it directly on the rack helps to ensure even heating and a crispier crust.
Bake for 5-10 minutes: Bake the loaf for approximately 5-10 minutes. The exact time will depend on the size and density of the loaf. Keep a close eye on it to prevent it from burning.
Check for crispness: The loaf is ready when the crust feels firm and crisp to the touch. Remove it from the oven and let it cool slightly before slicing and serving.
For an extra-crispy crust, try placing a baking sheet filled with water on the bottom rack of the oven while reheating the bread. The steam created will help to rehydrate the crust and create a wonderfully crisp exterior. However, be careful when removing the hot water-filled baking sheet from the oven.
