Begin by rimming your serving glass with a lime wedge and dip it into kosher salt.

In a high-speed blender, combine silver tequila, cold water, lime juice, agave or simple syrup, pineapple, mint leaves, cilantro, and jalapeño slices. Blend until smooth.

Check the consistency; add cold water if too thick and blend again until desired texture is reached.

Pour the mixture into your prepared glass filled with ice cubes. Garnish with cilantro or mint, and serve.
