Do you have to use cream? I highly recommend using real cream because it really adds to the richness of this soup. However, in a pinch you can substitute half-and-half or whole milk.
Storage: Store covered in the refrigerator for up to 4 days. To reheat, return to a large stockpot and reheat the remaining soup over medium heat until heated through. To reheat a single serving, place in a microwave safe bowl and microwave for 1-2 minutes, or until heated through.
Freezer Directions: Prepare soup according to recipe instructions. Allow soup to come to room temperature, and then transfer to a freezer dish or bag. Freezer for up to 3 months. Thaw in the refrigerator overnight to use. Reheat in large pot over medium heat until heated through. For fresher, crisper spinach, add it after freezing while reheating.
