For Croutons
Cream soups are the best made just before serving, especially when using green vegetables, as the soup can lose some of its vibrant color. You can make (without blending) the soup base the day before; let cool completely then refrigerate in an airtight container. When ready to serve, heat the soup base, wilt the spinach into the heated base, and blend.
