This is an old one I had forgotten the portions to for well over a year. I for a period of time (before caring about cost) was completely opposed to compound flavor syrups. I thought, as a newer bartender it retarded understanding the process and the product, so I set out to use only spirit and citrus with no added sugars or flavors. This was my first shot at it 5 years ago. It's still a go to for me when I can remember it.
1.5 oz. Bulleit rye (Willett single barrel rye would rock)
