First squeeze and measure out the fresh juice. If you plan to garnish the cocktail with lime peel, make sure to remove a large strip of the peel before cutting and juicing. Wrap the peel around a straw or something thin and round to set while you work on the rest of the drink.
Next, measure out the rest of the ingredients and then add everything to a shaker. Top with ice, close the shaker, and vigorously shake everything for about 30 seconds.
Double strain using a hawthorne strainer and a fine mesh strainer into either a chilled coupe glass (sans ice) or a chilled rocks glass (with a large ice cube/or medium cubes). Garnish with the twisted peel, if you made one.
Notes
To batch this cocktail, multiply the ingredient quantities accordingly. Keep in mind that two things: 1. Freshness is key when it comes to citrus juices, so it's best to pre-mix the other ingredients and then squeeze and mix in the juice just before serving to ensure optimal flavors. 2. Add a little water to the mix to represent ice melting during shaking the cocktail.
You can also garnish this cocktail with a grapefruit or lime wedge.
