Tamarind Margarita

Ingredients

1. 1 tablespoon tamarind pulp (see Note)
2. 3 tablespoons water
3. 1 cup Herradura Silver tequila
4. 2 tablespoons superfine sugar
5. Crushed ice
6. 1/2 cup plus 2 tablespoons fresh lime juice
7. 1/4 cup Cointreau
8. 2 tablespoons fresh orange juice
9. 1 1/2 tablespoons kosher salt mixed with 1 teaspoon finely grated orange zest
10. 4 lime wedges

1. In a saucepan, simmer the tamarind and water over low heat, stirring, until the pulp dissolves. Press the mixture into a shaker through a fine-mesh sieve. Add 1/2 cup of the tequila and the sugar; shake vigorously. Add ice to the shaker, then add 1/2 cup of lime juice, the Cointreau, the orange juice and the remaining 1/2 cup of tequila; shake well.
2. Pour the remaining 2 tablespoons of lime juice and the salt mixture into 2 bowls. Dip the rims of 4 old-fashioned glasses first in the lime juice and then in the salt mixture. Fill the glasses with ice. Strain the drink into the glasses and garnish with the lime wedges.
