watermelon 14.4 oz 408 g 3 cups cubed
green apple 1.17 oz 33 g 1/5 medium apple
beet (red variety) 0.36 oz 10 g 1/10 beet
lime 0.23 oz 7 g 1/5 lime
fresh mint 0.11 oz 3 g 3-4 mint leaves
chili pepper (optional) 0.09 oz 3 g serrano variety


  1. Wash the produce.

  2. Remove the watermelon rind (optional, see pro tips below), weigh, cube, then place directly into the juice press chamber.

  3. Weigh the rest of the ingredients.

  4. Grind the rest of the ingredients and press.

Pro Tips

  • You can actually leave the watermelon rind on if you prefer (there are nutrients in the skin) but the juice will look less vibrant and will mellow the flavor a bit. If it is not that sweet, I would definitely peel.

  • If the mint stems are green and soft you can juice those as well.

  • You can remove the serrano chili pepper seeds for a milder flavor or keep them in for added heat.

    Not super into the spicy but pretty interesting. Without chilies it’s A+

    Good recipes but I’d like to know if I can just use a blender and get the same results.


    1. Hi Kevin,

      You can use a blender, but it will definitely taste a little different and have a different mouth-feel. You can see more about the differences between blending (smoothies) and juicing here: https://www.goodnature.com/blog/juice-vs-smoothies/

    Perhaps you meant to say to place the lime in the press as well, yeah? 🙂

    Thank you for the sweet (and spicy) ideas! Grateful!


    1. Hello, Correct, you can place the lime quartered unpeeled directly into the press ad skip grinding, or peel the lime and grind with the other produce.
