With its trio of Italian liqueurs, and a pour of barrel-aged grappa that's less than half the combined volume of the liqueurs, this old-fashioned alternative...
I reduced the recipe by a fifth (4cl Grappa, 2.5 limoncello, 1.5 Amaretto and 1.5 Galliano) and I honestly feel like it's still too big. Aside from that it actually took me by surprise. The Amaretto works fabulously with the aged Grappa, the Galliano brings some herbal complexity and the limoncello brings it all together under a citrus umbrella. It's a sweet cocktail, yes, but it all works together.
