Key Ingredients
This simple recipe has only four key ingredients!
Apples: I like to use fuji apples in this recipe, but gala apples will also work well. My article on the differences between gala vs. fuji apples will help you determine which you will enjoy more. Look for apples that are firm and have a deep red color. You can also add more apples if you want a sweet taste.
Kale: Many types of fresh kale will work in this recipe. I've used curly, lacinato, red Russian, and kalette. I like to use lacinato kale in my smoothies and juices because it has a milder flavor, and the leaves are more tender, which makes it easier to blend.
Cucumber: To prepare a cucumber for a juicer, you should first wash it with cold water and scrub the skin with a vegetable brush. Then, cut off the ends and peel off any tough skin. I like to use English cucumbers because they have thinner skin and fewer seeds.
Lemon: Make sure you peel away the skin of your lemon before adding it to the juicer for best results. You can add lemon juice to the smoothie in a pinch if you don't have a fresh lemon on hand. I've done this several times! Make this strawberry lemonade vodka drink to cool down with your extra lemons!
Equipment
I recommend looking at some of the best juicers to determine the best bet for your price range. Brands such as Nutribullet and Hamilton have reasonably priced juicers that will work well for your home kitchen.
You can still make this recipe if you don't own a juicer! In this case, you'll want a fine mesh strainer or cheesecloth. You'll blend everything in a blender and pour the mixture through to remove chunks and fibers. Either of these methods works just fine!
Heather's helpful hints
Cut up fruits and vegetables into smaller pieces before adding them to the juicer to make it easier to juice.
If you use a blender, blend softer fruits and vegetables first. Then add your harder fruits and vegetables gradually to the juicer.
Make sure you tackle clean-up right after you finish using your juicer. The longer your dried pulp sits around, the more challenging it will be to clean. I sometimes rinse mine and throw it into the dishwasher.

Storage
I recommend drinking your juice as soon as possible for maximum nutrition and flavor. If you're not drinking it immediately, you can store the juice in an airtight container and consume it within 24 hours. After making it at home, I often use a mason jar to transport my juice to work. I do not recommend storing your juice in the freezer.

Susan
I love First Watch, and this was the second recipe I used to make their kale tonic. The other one didn't work out for me. Thanks so much, Heather. Do you think I could double this and make four servings for the week?
Heather
Hi Susan, I'm so glad this worked out! It's a fave breakfast spot for our family. I usually don't recommend making too much of this recipe in advance. I'd say two days tops in the refrigerator, although ideally, you want 24 hours or less. Enjoy :)
