1. Muddle strawberries in a bottom of a cocktail shaker with the agave nectar or sugar, until the berries are almost completely liquified. 2. Add the tequila, lime juice and orange liqueur. Fill the shaker about halfway with ice, and shake for 15 to 20 seconds, until the mixture is very cold. 3. Remove the lid and strain through a julep strainer or coarse mesh strainer into a chilled coupe glass, or short tumbler half full of ice. Garnish with a lime wheel.
