Add the apple juice, lemon juice, and maple syrup to a large pitcher and stir well.
NOTES Apple juice is naturally quite sweet, so you can easily make this a sugar-free lemonade simply by omitting the maple syrup. It's delicious without it, too.
FAQS Can I use honey instead of maple syrup? Yes, you can. But when honey meets cold apple juice, it thickens and doesn't mix well.
