Instructions

1. 1

   Juice your lemons fresh

   Roll a room-temperature lemon firmly against your cutting board to break the internal membranes. Halve and juice it, straining out seeds and pulp. Measure precisely. Too much lemon and the drink becomes a pucker; too little and it's cloying. The three-quarter ounce measure exists for a reason.

   Lemon juice begins to oxidize within hours. Bottle lemon juice is dead on arrival. Squeeze it fresh every time or don't bother making this drink.
2. 2

   Prepare the simple syrup

   If you haven't made simple syrup ahead, combine equal parts sugar and hot water in a jar and shake until dissolved. One cup of each yields enough for a dozen cocktails. Let it cool before using. Warm syrup throws off your dilution calculations.

   Store simple syrup refrigerated for up to a month. Add a splash of vodka if you want it to last longer. The alcohol prevents fermentation.
3. 3

   Choose your path: classic or foam

   Decide now whether you want the silky foam cap. Both versions are correct. The original nineteenth-century recipe included egg white; the streamlined modern version often omits it. Egg white adds body, softens the citrus edge, and creates a dramatic presentation. Without it, the drink is brighter, more direct.

4. 4

   Combine in shaker

   Add the bourbon, lemon juice, and simple syrup to a cocktail shaker. If using egg white, add it now. The order matters less than the precision of your measurements. If using bitters, wait until the very end.

5. 5

   Execute the dry shake (egg white version only)

   If you've added egg white, seal the shaker and shake vigorously for fifteen seconds without ice. This is the dry shake. It emulsifies the protein, creating the foam that will crown your drink. You'll hear the liquid sloshing freely. Shake until you feel the mixture become slightly resistant, almost creamy.

   The dry shake is not optional for egg white cocktails. Skip it and you'll have wispy, insubstantial foam that disappears in seconds.
6. 6

   Add ice and shake hard

   Fill your shaker two-thirds full with ice cubes. Seal tightly and shake aggressively for twelve to fifteen seconds. You want the outside of the shaker to frost over and become almost painful to hold. This chills the drink properly and provides the correct dilution. The ice is doing work here, not just sitting there.

   A proper shake uses your whole arm, not just your wrist. The ice should sound like a freight train inside that tin.
7. 7

   Prepare the serving glass

   Place a single large ice cube or sphere in a rocks glass. Large format ice melts slowly, keeping your drink cold without diluting it into water by the final sip. If you don't have large ice molds, two or three standard cubes will do.

8. 8

   Strain and serve

   Strain the cocktail over the ice using a Hawthorne strainer. For the egg white version, double-strain through a fine mesh strainer to catch any ice shards that would mar the foam's surface. Pour slowly, letting the liquid slide down the ice. The foam will rise and settle into a thick, creamy cap.

   Let the drink rest for ten seconds after pouring. The foam firms up and the layers settle beautifully.
9. 9

   Add bitters and garnish

   If using Angostura bitters, dash them onto the foam now. They'll sit on the surface in dark droplets. Drag a toothpick through them to create a simple pattern if you're feeling theatrical. Float the lemon wheel on the foam or tuck it against the ice. Skewer your brandied cherry and rest it across the rim, or drop it into the drink where it belongs.

Chef Tips

• •The 2:3/4:3/4 ratio is your foundation. Two ounces spirit, three-quarter ounce each of sour and sweet. Once you internalize this formula, you can build dozens of sours by simply changing the spirit.
• •Seek out Luxardo or Amarena cherries for garnishing. Those neon red maraschinos from the supermarket are corn syrup and red dye. They belong nowhere near a proper cocktail.
• •For batching: multiply all liquid ingredients by the number of servings. Combine everything except ice in a pitcher and refrigerate. Shake individual servings over ice when guests arrive. The drink takes thirty seconds to assemble when your mise en place is ready.
• •Separate your egg whites ahead of time and hold them refrigerated. They're easier to work with when cold. Use the yolks for carbonara the next day.

Advance Preparation

• •Simple syrup keeps refrigerated for up to a month and should always be on hand in a proper home bar.
• •Juice lemons up to four hours ahead and refrigerate. Beyond that, the brightness fades noticeably.
• •For entertaining, combine bourbon, lemon juice, and simple syrup in a pitcher up to two hours before guests arrive. Shake individual portions with ice and egg white to order.
