I dropped the pineapple juice since I didn’t have it this time and used a half ounce of simple syrup. The caramel stands out much more this way. I think I’ll do it moving forward.
I've tried this with both Tennessee whiskey and rye. In my opinion the spiciness of rye adds some depth that the Tennessee whiskey lacks. But then again, I prefer rye to Tennessee whiskey so I may be a bit biased.
