Ah, the classic Paloma: it's tart, refreshing, and easy to make. The salt rim is optional, but it adds an enjoyably savory dimension. If you're looking for an extra kick, try rimming your glass with Tajín.
2 oz reposado tequila
.5 oz lime juice
Garnish: rim glass with lime wedge and salt (optional), fresh herbs and grapefruit or lime wedge
Stir all ingredients together in an ice-filled glass and garnish if desired.
