Add the margarita ingredients to a shaker or mason jar, fit with lid, and shake well. 2. To make the salt, combine zest and coarse salt together with a fork until well incorporated. Transfer to a plate to make it easier to dip the glasses. (Makes enough salt for at least 4 drinks). 3. Run a citrus wedge around the edge of your glasses, and dip each glass into the citrus salt. 4. Fill glasses with ice, and pour margarita mixture evenly into both glasses (I used 8 oz rocks style glasses). Garnish with citrus and serve! Bonus: Lemon Twist GarnishTo make the lemon peel twists, cut a strip of lemon peel with a pairing knife, edge-to-edge around the circumference of the lemon. Gently twist in opposing directions on the ends and hold to shape. Release and form as desired (should be nice and spiraled, but pushing it a bit can give it more definition/tighter spiral).
