This style of cocktail is known as a 50/50 due to its equal parts of 2 base ingredients. Good 50/50 pairings are often surprising in their depth of flavor given the simple template, showcasing how thoughtful pairing of spirits can often be greater than the sum of their parts.
Very similar to the [Mezcaletti](/mezcaletti.html), but with Ramazzotti Amaro instead of Meletti.
