As the name suggests, this cocktail is dominated by amaretto, with lemon juice providing the sour balancing element and a slug of bourbon giving backbone.

Switch simple syrup with some cherry syrup (if you have it) such as Luxardo Maraschino Cherries, it will be more complex. Amaretto pairs well with cherry.

Made a while ago, brilliant. Made it last night but with rye and, yup, still absolutely brilliant.

Is this supposed to be brown sugar or brown sugar syrup? (Because ml/oz is an unusual way to measure brown sugar...)

Thanks, Peter. It should indeed say brown sugar syrup. Now corrected.

I made two for a side by side comparison, one with Bulleit Bourbon and one with Tincup Rye. The rye won out for me. Both are very nice. My wife preferred the traditional (no whiskey). I preferred this but with rye.

I love how this recipe is still spectacular with a budget amaretto like Di Amore and a serviceable, if not stellar bourbon like Evan Williams bottled-in-bond. What balance!

Made many a batch of this over the years. Works great with a lot of spirits besides burbon.
Some notable ones are Aberlour A'bunadh, Goslings 151 and DonQ 151 (although in that case omit the sugar), and Chateau de Lacquy 12y.

Give it a spin when feeling adventurous.

I didn't have any bourbon handy, so I used Busker Irish instead. Turned out very nicely.

We had this for the first time last night. I can't believe I haven't made it before. We made it with Billington's muscovado sugar, which you can taste in the resultant cocktail. It was gorgeous. In a rocks glass, with one, giant ice cube. Thoroughly recommend.

I think this cocktails needs something like Rare Breed or Knob Creek Single Barrel mainly because the amaretto is just a touch too sweet and seems to hit a lot of things over the head with an almond shaped brick.
