It has every element a sour cocktail should have - it's slightly sweet, perfectly tart, and has a hint of bitterness. It's a perfectly smooth and not too sweet combination of Amaretto, sour mix, and bourbon.
Combine fresh squeezed lemon juice, simple syrup, Amaretto, and bourbon in a cocktail shaker. Add a few ice cubes and shake vigorously.
Add some ice into a rocks glass and strain the cocktail into it. Optional: if you prefer to use "dirty ice" from the cocktail shaker, don't add any ice into the rocks glass and just pour everything into the glass from the cocktail shaker.
If you wish, add a splash of soda water to the cocktail. Garnish with an orange twist and cocktail cherries.
