Begin by salting the rim of your cocktail glass (optional). I like to use margarita salt with honey for a nice strong salted rim.
In a cocktail shaker, combine tequila, orange liqueur, fresh lime juice, agave and strawberry purée with ice. Shake for 10-15 seconds.
Pour the mixture into your rimmed glass over fresh ice. Garnish with a fresh strawberry or a lime wedge on the rim (optional).
Notes
If you want to skip the strawberry purée step, you can muddle some fresh strawberries with simple syrup in the bottom of your glass before making the same recipe (minus the purée)—kind of like the Strawberry Mojito. I personally really loved the texture and flavor or the purée and consider the step worth the effort!
When it comes to margaritas, I always use fresh squeezed lime juice. It's worth it.
If you don't have tequila blanco on hand, you can substitute for reposado tequila or gold tequila. You can even sub in mezcal if you wish.
