I saw this done on Facebook and decided to give it a go. I juiced one type of produce at a time: Green apples to the left, Kale in the middle (what I had left), and Carrots to the right. Then I saved the pulp from each type in it’s own freezer safe bag. Now, I can mix and match this juice i.e. carrot, apple, kale or just carrot and apple with ginger or lemon or kale and carrot with lemon…you get the idea. If I had more veggies I would have done more. I will do the same for my lemons and ginger. Happy juicing!
