How to Pick a Ripe Melon

I’ve spent a lot of time at the market picking up watermelons to try and find the perfectly ripe one. Yet, I have no idea what I’m doing. I want to blend this melon smoothie ASAP! So I Googled ‘how to pick a watermelon’ and got some great tips from The Pioneer Woman:

  1. It should be heavy (small or large)
  2. There should be a side that’s more yellow, from it sitting on the ground
  3. Once you find the yellow spot, knock on it. If it sounds hollow, then you’ve got a winner!
  4. Take it home, cut it up, and blend this melon smoothie before anyone else gobbles up all the watermelon!

Smoothie Swaps

Watermelon is a unique fruit for smoothies, because it has 2 purposes: fruit + liquid. I recommend adding 1 cup of liquid to most smoothie recipes, yet when it comes to watermelon, I lower the amount of actual liquid to compensate for the load of water inside the melon.

In fact, this melon smoothie has NO LIQUID… and that’s on purpose. I want my smoothie to be drinkable, yet not juice. The 1 1/2 cups of juicy watermelon gives me all the water I need for this beverage.

If you’re needing to swap out the watermelon, I suggest swapping for another fruit in the family: cantaloupe, zucchini, or muskmelon. Swaps will change the taste, so you might need to add a bit of maple syrup to keep this melon smoothie sweet with any substitutions you make.

What fruit goes well with melon?

Berries! Herbs! Leafy Greens! Oh… but for real. All of these are great additions to this summertime fruit. I like pairing it with berries because they add sweetness + tartness to the mix, all while keeping the natural sugar content low.

What are the best fruits to put in a smoothie?

What’s your fav fruit? Answer, then toss that into your blender! I add at least 1 frozen fruit to ensure a refreshing smoothie, yet all kinds of fruits go great in smoothies.

How do you make a smoothie with watermelon?

The biggest key is not adding too much liquid. Watermelon is already full of water, so try leaving out any extra liquid first, then add a bit of water if needed after your first blend. This melon smoothie should have plenty of liquid without adding any extra.

  1. I liked this one. I substituted blueberries for the blackberries and it had a nice refreshing flavor

    I made the mistake of freezing this recipe ahead of time and found the watermelon too hard to blend. I let it sit 10 minutes and then added some strawberry lemon kombucha (homemade) to get things moving. It turned out to be super tasty!

  3. Although it didn’t looks as appealing as other smoothies, it was tasty. I’m not a huge fan of melon in smoothies, but this one works thanks to the berries.

    Made this as a breakfast smoothie by adding Greek yogurt, oats, matcha, and the magic trio (hemp hearts, flax seed, chia seeds). Because the flavours of the fruits can be subtle I found the hemp hearts flavour to be more forward than other smoothie recipes I’ve tried on this site. I still found it tasty but it might be off-putting for some.

    Made this one last night. Had to work very early and didn’t want to wake the hubby with my vitamix lol. Was a bit short on watermelon so I added a couple chunks of cantaloupe. Still tasted great.

    Mmmmm! I used a mix of blackberries, blueberries and raspberries along with the watermelon and spinach. Also added carrot tops and hemp hearts. Plus I added some water to thin it out.

    Five Star Rawk! I really liked this smoothie. I used a juicy sugar baby watermelon that was naturally sweet enough to satisfy my sugar cravings. I thought it offered a good balance with the lower sugar berries. Did I need to add liquid? Nope! I used the tamper to move the ingredients around in my blender and let the blades do the work. I did a full blend and did a few seconds of a second round to make sure it was smooth!
