Why This Mocktail is More Than Just a Pretty Drink

This watermelon jalapeño mocktail isn’t just delicious—it’s packed with fresh, real ingredients that actually benefit your body:

Watermelon – Super hydrating (90% water), packed with vitamin C for skin health, and rich in lycopene, an antioxidant that supports your heart.

Jalapeño – Adds flavor and fire. Thanks to capsaicin, it may help boost metabolism and support digestion.

Mint – Calms the stomach, supports digestion, and gives the drink a refreshing twist.

Lime – High in vitamin C and adds the perfect citrus zing.

Club Soda – Keeps it light, bubbly, and helps aid digestion too.

How to Make This Watermelon Jalapeño Mocktail

You don’t need fancy tools, but if you want to make your life easier, I highly recommend using a cocktail shaker. It helps muddle and mix everything perfectly.
Get a cocktail shaker like this one — it’s simple, affordable, and makes you feel like a pro.

Notes & Tips:

• Not a fan of fruit chunks? Use 1/2 cup fresh watermelon juice instead of muddled cubes.

• Want it sweeter? Add more grape juice or a drizzle of honey or agave.

• Prefer less spice? Remove the jalapeño seeds or start with just one slice.

• Chill your ingredients ahead of time so you don’t have to rely on ice to keep it cold.
