This frozen watermelon slushie cocktail is the perfect way to cool down with friends on a hot summer night. It's made with just 4 simple ingredients and can be enjoyed with or without alcohol.
Whether I'm having a cocktail or mocktail, or I just want something refreshing like a glass of lavender lemonade, I find that the homemade option is always the move. Pre-made mixes are usually way too sweet and sometimes also have unnecessary additives.
If you live in a hot climate in the summer, which is basically everyone now, you know that cold beverages in some form are 100% necessary to survive the heatwave. Which is why this frozen watermelon slushie always hits the spot.
Ingredients For Watermelon Slushie Cocktails
- Watermelon - the riper and juicier the better.
- Fresh lime juice - helps to balance out the sweetness.
- Clear alcohol of choice - tequila, vodka, gin, or white wine.
- Simple syrup - basil, lime, or strawberry simple syrup would be amazing! But plain is great, too.
- Flaky salt - optional.
Substitutions & Variations
Please remember that recipes are just a starting point.
How can you make this watermelon slushie cocktail using what you already have? Here are some ideas…
- Don't drink alcohol? - use water or coconut water in place of the alcohol (I personally love the mocktail version. Plus, it's also kid-friendly.)
- No fresh lime juice? - Pure lime juice in a jar also does the trick.
- No simple syrup? - maple syrup will work, but I highly recommend the simple syrup for a clean finish.
- Variations - try other kinds of melon and get creative with infused simple syrups to create endless variations.
Equipment
A high-powered blender works really well for getting a smooth yet frozen consistency, using the tamper as needed. If you only have a standard blender, you may need to blend the watermelon cubes in smaller batches and/or stop and scrape down the sides as needed.
You could also try making it in a food processor.
Top Tip
The simple syrup helps to intensify the flavor of the watermelon. How much you add will depend on how sweet your fruit is, so adjust accordingly.
