We recently got a juicer (for free!) through a rewards program at my husband's job. I remembered that there was a juice recipe I wanted to try awhile back that involved apple and ginger, but we'd had no juicer at the time. I couldn't find the exact blog (apparently I hadn't pinned it to any of my Pinterest boards) But I searched Pinterest and found a recipe for Apple Ginger Carrot juice.
2 apples... 7 carrots... 1 piece of ginger "the size of your thumb". (although make sure it's the size of your own thumb and don't round it up to the size of your husband's big ol' thumb...because the juice turns out a bit too spicy then!)
