cups raw baby spinach leaves*
cups fresh or frozen blueberries (no syrup or sugar added)
teaspoon lemon juice
note: I prefer raw baby spinach to frozen spinach for this recipe (more mild flavor); if you must use frozen spinach, only use 1 cup of it.
> Thoroughly wash the spinach, even if the package says “prewashed.” If using frozen blueberries, quickly rinse them under cold water to thaw a little, and then drain. > Fill the bowl of your food processor with the spinach, blueberries, lemon juice, and 1 tablespoon of water; puree on high until as smooth as possible. Stop occasionally to push the contents to the bottom. If necessary, use another tablespoon of water to smooth-out the puree. > This recipe makes about 1 cup of puree; double it if you want to store another cup. It will keep in the refrigerator up to 3 days, or you can freeze 1⁄4-cup portions in sealed plastic bags or small plastic containers.
