Delicious and Refreshing Smoothie Recipe

The blend of fresh, sweet watermelon and tart lemons gives you a delightful and refreshing experience. In other words, you’ll love these smoothies! Basically, it’s delicious and helps you stay cool on the hottest of days.

Every year in late May or early June, I start craving watermelon. My husband is like that with lemonade.

So how can you go through the summer without watermelon … and lemonade? You don’t have to. Combine the two, and you have the most refreshing drink in town. Both my husband and I agree that this blend is perfectly satisfying for both of our cravings.

Imagine yourself sitting out on the front porch or on the back lawn on a warm summer day. Whether you’re reading a book or chatting with the neighbor, this drink will cool you off and make the experience even more enjoyable.

But it’s even good when it’s not hot out. If you like watermelon, you’ll love this smoothie. It’s like a vacation every single time you take a sip.

Sounds so yummy and refreshing! And about the previous comments, in Mexico, limeade is often made with whole fruits blended in; it is delicious, but it must be consumed almost right away before it turns bitter.

My son adores watermelon slices and also loves to make smoothies...only trouble he never drinks them afterwards. I'm crossing my fingers we can merge the two and I can get him to make these with me AND drink it too!

I hope your son drinks it and enjoys it! We love smoothies, and this is one of our favorites!
