Measure out the crushed ice and add it directly into your blender.
Pour in the tequila, lime juice, triple sec, and simple syrup over the ice.
Secure the lid and blend on high speed until the mixture is icy, smooth, and slushy, about 30-45 seconds. You should hear a consistent crunching sound and see a frosty texture forming.
Check the consistency; if it’s too thick, add a splash of water and blend briefly. If it’s too thin, add a bit more crushed ice and pulse again.
While blending, prepare your glasses by rimming the edges with salt if desired, pressing them gently into a plate of coarse salt.
Once the mixture is smooth and frosty, pour it into the prepared glasses, filling them to the brim with a satisfying icy mound.
Garnish with a lime wedge on the rim for a colorful and fragrant finishing touch.
Serve immediately with a straw, and enjoy the icy, tangy refreshment that’s perfect for sipping on a warm day.
