Yes! Once you have prepared the sauce, allow it to cool completely. Then, transfer it to an airtight container and refrigerate it for up to 3-4 days. When you're ready to use it, simply reheat the sauce gently on the stovetop or in the microwave, stirring occasionally to ensure even heating. You may need to add a splash of milk or cream to adjust the consistency, as the sauce can thicken when refrigerated.
