Fill a highball glass with ice cubes, followed by blanco tequila and the juice from the half lime. Top with chilled Topo Chico. Add a fresh lime wedge to the rim of the glass and serve. Makes one cocktail.

Fruit variations: Squeeze fresh orange or grapefruit juice, or pureed watermelon, strawberries, kiwi, or another favorite fruit in a blender. Add 1 ounce of fruit puree to Texas Ranch Water, stir, garnish with fresh mint, and serve.

For a spicy version of Ranch Water, place one or two slices of fresh jalapeño in a highball glass. Muddle the jalapeño with a wooden muddler or spoon. Add ice, tequila, lime juice, and Topo Chico. If you like, garnish with jalapeño and a wedge of lime. Enjoy!
