Homemade Watermelon Juice

June 13, 2018

Redeem mediocre watermelons by turning them into homemade watermelon juice! All you need is cubed fruit, lemon juice, a sweetener, and a blender!

This is a tale of a mediocre watermelon and its eventual redemption. It all started last week, during a trip to Trader Joe’s. They had a bin of watermelon in the entry way and I was entranced. You see, I am one of the people who can eat endless amounts of watermelon and in the height of summer, I often work my way through a couple sizable melons per week (my husband does not partake. He is strictly a cantaloupe man).

I tapped a few melons and lifted a couple possible candidates into the air, hoping to find a good one using both science (hollow sound) and intuition (feel). Hoping for the best, I finally hefted a gorgeously striped watermelon into my cart. Walking home with one bag on my shoulder and the watermelon cozied up in my favorite mesh sack, I was so looking forward to eating a bowl of melon cubes.

I think you know what comes next. The melon I had so carefully chosen was not a winner. It was pale, mealy, and barely sweet. For a moment, I contemplated bagging it up and taking it back to Trader Joe’s for a refund. But then, I realized there was an answer.

The prior weekend, I had spent some time with a friend who had mentioned how much she liked the watermelon juice sold at a local-to-her taco truck. I cubed the watermelon and threw it in the blender with the juice of a lemon (lime would have also been good) and a tablespoon of agave nectar (I had a bottle that was nearly kicked and I wanted to use it up. Honey or even maple syrup would also be good).

The additional acid and sweetness brought the watermelon into balance and it became a truly delightful drink. It kept in the fridge for about 48 hours. It did separate a bit as it sat, but could be brought back together with a quick shake.

I’m not going to offer a specific recipe because every watermelon will be different (and some won’t want any additional sweetness at all). But if you find yourself in possession of a lackluster melon this summer, instead of bemoaning your fate, turn it into juice!

  • I love watermelon juice! Ever since I had it as a kid in Taiwan, it is one of my favorite summer drinks. It certainly is a great way to turn a less than stellar melon into something refreshing, or to finish up some leftover watermelon.

    Sometimes I add a little bit of ice, and the latest thing for me has been to add fresh mint and lime.

  • When I was expecting my oldest daughter, I craved watermelon. I ate a whole one every day. Luckily, I was expecting in the summer. She was born at the end of August. Almost 50 years ago. Wow. Time flies.

  • We love to make Agua Fresca with watermelon in the summer…to use up so-so watermelon, like you did, or if we buy a huge one and get tired of it. I risked buying one this week with the plan to make agua fresca for a graduation party this weekend. Great idea!

  • My favorite way to use mediocre watermelon is in a smoothie. I fill the blender 3/4 full with watermelon then add about 1/2 cup vanilla yogurt, lime juice, ice, a squeeze of honey and then either a bit of ginger or even ginger powder in a pinch. It’s seriously delicious!

  • I eat watermelon every chance I get but if it’s cubed and sitting in the fridge for long enough to get a little “rubbery” and I’m no longer enjoying it raw, I throw it into smoothies, freeze it for smoothies later, or just blend it up like you have done here and drink a tall pint of it. So refreshing and nutritious. Great idea!

  • Try picking a watermelon by the yellow spot where it sat on the ground. The brighter/more intense the yellow the riper the melon should be.

  • Long ago a man I knew from India made me a watermelon milkshake I had never heard of this but I am always interested in different foods. It was cubed watermelon in a blender with about equal parts milk, sugar and rose syrup. Whirred in the blender it was so refreshing and unusual, it was the first time i ever tasted anything rose flavored. Your article reminded me of this and I think I will try to make this soon, I wonder what it would be like if I substituted vanilla ice cream for the milk? Cheers

  • I freeze watermelon juice into cubes and in the winter months add to a glass of water. Tastes so refreshing as it melts.
