I really enjoy the Boulevardier so this recipe caught my eye. I used Bulleit bourbon, Blackwell's and Campari. I slightly oversalted (1 teaspoon solution). To remedy, I added a drizzle more water and rum. That calmed things down but, however palatable, this doesn't significantly improve on a Boulevardier. But ... I learned about saline and about water and I now have more decent rum in my cabinet so I'm looking on the upside.
