A few margaritas on the rocks with a friend is the best way to enjoy a Sunday afternoon in Valladolid, Mexico. Adding two tequila sidecars only makes things better.
1 1/2 oz Tequila
1/2 oz Cointreau
1 oz fresh lime juice
Shake all ingredients with ice and strain into a salt-rimmed glass with ice. Add a lime wheel to garnish. Double the ingredients to make two cocktails.
