How To Store / Freeze Your Pie
Allow the rhubarb custard pie to cool completely at room temperature. This helps the custard set properly and makes it easier to handle.
Once cooled, cover the pie loosely with plastic wrap or aluminum foil. This prevents the pie from absorbing any unwanted odors from the fridge.
Store the covered pie in the refrigerator. It can be kept for up to 3-4 days. The custard will remain creamy, and the rhubarb will retain its delightful tartness.
If you wish to freeze the pie, first ensure it is completely cooled. Wrap the pie tightly in plastic wrap, followed by a layer of aluminum foil. This double wrapping helps prevent freezer burn and preserves the pie's texture.
Label the wrapped pie with the date to keep track of its freshness. The rhubarb custard pie can be frozen for up to 2 months.
When ready to enjoy, thaw the pie in the refrigerator overnight. Avoid thawing at room temperature to maintain the integrity of the custard.
For a slightly warm serving, reheat individual slices in the microwave for about 15-20 seconds. Alternatively, you can warm the entire pie in a preheated oven at 350°F (175°C) for about 10-15 minutes. This will revive the custard and rhubarb flavors beautifully.
Always use a sharp knife to cut through the pie, ensuring clean slices without disturbing the delicate custard filling.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover rhubarb custard pie on a baking sheet and cover it loosely with aluminum foil to prevent the crust from over-browning. Heat for about 15-20 minutes or until warmed through. This method ensures the custard remains creamy and the pie crust stays crisp.
For a quicker option, use a microwave. Place a slice of the pie on a microwave-safe plate. Heat on medium power for 1-2 minutes, checking every 30 seconds to avoid overheating. This method is convenient but may result in a slightly softer crust.
If you prefer a more even reheating, use a toaster oven. Set it to 350°F (175°C) and place the pie inside for about 10-15 minutes. This method combines the best of both worlds, offering a crisp crust and warm custard.
For an extra touch, reheat individual slices in a skillet over low heat. Cover the skillet with a lid and heat for about 5-7 minutes. This method can give the pie a slightly caramelized bottom, adding a delightful texture contrast.
