Jigger or measuring tool for accurate pours
Strainer (Hawthorne and fine mesh) for a smooth pour

Instructions

The key technique is the "dry shake" followed by a "wet shake" to build a rich, stable foam. Double straining ensures a silky-smooth texture in the final drink.

1. Combine amaretto, bourbon, lemon juice, simple syrup, and egg white in a cocktail shaker.

2. "Dry shake" (shake without ice) vigorously for about 15 seconds to emulsify the egg white and create foam.

3. Add a generous amount of cubed ice to the shaker.

4. "Wet shake" (shake with ice) hard for another 10-15 seconds until the shaker is well-chilled.

5. Place a large ice cube or sphere in a chilled Old Fashioned glass.

6. Double strain the cocktail through a Hawthorne strainer and a fine mesh strainer into the glass.

7. Express the oils from a lemon twist over the surface of the drink.

8. Garnish with the lemon twist and a brandied cherry.

Garnishing

Garnish with an expressed lemon twist to add bright citrus aromatics, and a brandied cherry for a classic visual touch and complementary flavor.
