1) Put the oranges, lemons, and limes through a juicer. Pour the juice into a large pitcher. Add the sugar and stir to dissolve. Then stir in the Cointreau, Triple Sec, and tequila.
2) To serve pour salt onto a small plate. Run a lime wedge around the top of each glass and dip the glass in the salt. Fill each glass halfway with ice and pour in the juice mixture. Garnish with a lime wedge and serve.
Chef's note: Farm freshness is the key here. Look for the citrus that is mostly in season and adjust the recipe. Tangerines, Meyer lemons, and key limes all have amazing flavour if you can find them.
