Notes

*To get 3 cups (750 ml) of juice, you’ll need about 6 cups (900 g) of cubed seedless watermelon. Blend until smooth, then strain through a fine mesh sieve for best texture or use Simply Watermelon juice (store-bought) if you want a shortcut. Fresh is the best though.
The simple syrup gets its flavor from steeping sliced jalapeño—not blending—so the heat stays smooth and consistent.
Using both granulated and brown sugar gives the syrup a rounder flavor that works well with the watermelon and tequila.
Reposado tequila holds its own here—don’t swap in blanco or it’ll get lost.
Add lime sparkling water right before serving so it stays bubbly.
The margarita base (juice, tequila, lime, syrup) can be made a few hours ahead and chilled.
Leftover syrup keeps in the fridge for up to a week and works in other cocktails or lemonade.
For one drink: ½ cup (120 ml) watermelon juice, 2 oz (60 ml) tequila, 1 oz (30 ml) lime juice, 1 tbsp (15 ml) syrup, and a splash of sparkling water.
