The Ingredients

Making these slushies couldn’t be easier considering they’re only three ingredients! Here’s what you need:
- Watermelon: Cut into chunks. Look for a ripe watermelon with a deep yellow field spot, a hollow sound when tapped, and dark green skin with a dull finish. These are signs it’s sweet and juicy.
- Fresh Lime Juice: Adds a bright, tangy contrast that balances the watermelon’s sweetness.
- Ice: Helps create that perfect slushie texture. Crushed ice works best if your blender needs a little help!
How to Make a Refreshing Watermelon Slushie

Step 1: Cut off the rind of a ripe watermelon and slice into chunks. Freeze the watermelon chunks for 4-5 hours and up to overnight.

Step 2: Toss the frozen watermelon chunks into your blender with the juice of one lime, some ice and voila! The most refreshing, hydrating slushie you’ll ever have!
Tips for The Perfect Watermelon Slushie
- Play with Variations: Feel free to get creative with your slushie. Add a handful of mint leaves for a refreshing twist, or throw in a splash of coconut water for added electrolytes.
- Balance the Lime: The lemon juice adds zing to the slushie, but adjust the quantity based on your personal taste preferences. Some like it tangier, while others prefer a milder touch.
- Serve Immediately: Slushies are at their best when freshly made. Serve immediately to enjoy the perfect texture and flavor.

FAQs
You don’t need a fancy blender, but a high-speed one handles ice better. If your blender is on the weaker side, use crushed ice instead of cubes. If you’re looking for a high speed blender, this is one of my favorites!
