Margaritas on the rocks can taste stronger than frozen margaritas since they are not blended with ice (or in our case water). You can add a little more tequila to your frozen mix or add a floater to the top of each glass, but be warned: these are deceptively STRONG margaritas! Start with a serving in the 4-6 ounce range rather than filling up one of those novelty giant margarita glasses...trust us!
