This works on the rocks just like a Negroni (use bigger ice if you are unsure you will enjoy the dilution). It is a bit less bitter, the orange stands out better, also the color is pink and fun. Depending on the triple sec this can be a less sweet, less bitter, more citrusy alternative to Negroni. Probably won't replace it in your repertoire but can find its way as a variation so we don't get bored.
