Rum has the flavor. Not having bourbon, I don’t know.
I got a bottle of bourbon from a friend as a present Christmas before last. As it turns out, it was the same brand of bourbon (”Four Roses”) that my dad & two of his buddies celebrated with when the end of WWII was announced. At the time, they were medical techs at an Army hospital in Hawaii (where hospital ships brought in Pacific Theater wounded) & they took a bottle up into the rocks/cactus behind the barracks to celebrate & got a bit snockered. Evidently, they weren’t the only ones .... not a lot of saluting going on that day, as he recalls.
So, the bottle was a gift in more than one way .... got my dad to recall a good end-of-the-war story. It also made for some really delicious bourbon balls. They were rather strong, but I like them that way. :-) Usually, I like rum better than bourbon, but I truly enjoyed this recipe with the bourbon.
