Mixing equipments
This cocktail requires a shaker to combine and chill the ingredients, and a strainer to ensure a smooth, foamy result. Accurate measurement is key to achieving the perfect balance.
- Cocktail shaker for shaking ingredients
- 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.
- Lemon twist, express oils over the drink and place on top
- Brandied cherry, drop one into the drink or place on a pick
