Swish the spinach around in the bowl for 1-2 minutes to wash away any dirt or bacteria. Then, hold it under cool running water from your sink and give it a good rinse to make sure it's completely clean. Even if you're pureeing and freezing it, you should always wash raw spinach before you eat it. If you're pureeing a lot of spinach, just put whatever fits into your blender at once. Then, add a splash of water, as this will help the spinach puree more evenly. You can also use a food processor, if you'd like. To make thawing your spinach puree as easy as possible, it's best to portion out just what you think you'll need at a time. To do that, you can divide the puree into snack-size freezer bags or freezer-safe baby food jars, or you can pour the puree into an ice tray to get small cubes. If you freeze the spinach in ice cube trays, wait until it's frozen, then pop out the cubes and transfer them to a freezer bag or another freezer-safe container. That way, you can re-use the trays when you need them. If your freezer stays at 0°F, the spinach will stay safe to eat as long as it's frozen. However, the quality will be best if you eat it within 10-12 months. To thaw the spinach, place it in the refrigerator overnight.  If you'll be using the spinach in a frozen smoothie, there's no need to thaw it first. Just toss it into the blender along with—or in place of—your ice cubes. You can also add frozen cubes of spinach directly to hot soups or other dishes while you're simmering them, since the heat will quickly melt the ice.
