There are a few ways to get the most juice out of leafy greens. The first is to use a juicer. A juicer will extract the juice from the greens and leave behind the pulp. Another way to get the most juice out of leafy greens is to blend them in a blender and then strain the mixture through a cheesecloth or coffee filter. This will remove any large pieces of fiber from the juice. Finally, you can also squeeze leafy greens by hand to extract their juice. This method is best for small batches of juice or if you don't have a juicer or blender on hand.
