FAQs
Do I have to freeze the watermelon first?
Yes, freezing the watermelon is what gives the drink its slushy texture without needing a ton of ice.
Can I use fresh watermelon?
You can, but the drink will be more watery and less frozen. Add more ice to compensate if needed.
What’s the best tequila for this?
Blanco tequila is ideal—it’s clean and doesn’t overpower the fruit. Reposado can work if you like a richer profile.
Can I use a different sweetener?
Yes, agave is traditional, but you can use honey, maple syrup, or a sugar-free sweetener to taste.
Is triple sec necessary?
It adds orange depth and brightness, but you can skip it or substitute with fresh orange juice.
How do I make a big batch?
Multiply the ingredients by the number of servings you need and blend in batches. Perfect for parties.
How many calories are in a skinny watermelon margarita?
Depending on ingredients and amounts, it’s roughly 150–180 calories—much less than a standard margarita.
Can I use a different fruit?
Absolutely. Try frozen strawberries, mango, or cucumber for a fun variation.
Can I add protein or collagen?
Sure—just make sure it’s unflavored or compatible with the drink. Blend well.
Is this gluten-free?
Yes, all the ingredients are naturally gluten-free—just double-check your tequila and triple sec labels.
