SHAKE: Add 1 cup ice, 2 ounces amaretto liqueur, and 1 ounce fresh lemon juice to a cocktail shaker. Secure the lid and shake vigorously for about 15 seconds, until the shaker feels very cold.
SERVE: Pour the cocktail into a rocks glass, including the ice.
GARNISH: Add 1 lemon or lime slice to the glass and serve immediately.
Notes
Make-Ahead: This cocktail is best made fresh. You can pre-measure the amaretto and lemon juice up to 1 hour ahead and keep chilled.Storage: Not recommended. Citrus juice dulls quickly once mixed.Ice Tip: Use fresh ice straight from the freezer for the cleanest flavor and best chill.Ingredient Note: Fresh lemon juice makes a noticeable difference. Bottled juice will taste flat in a simple two-ingredient cocktail.
