Campari and St. Germain, we wondered. Can it be done? Has it been done? Before rushing to concoct a brand-new and potentially problematic cocktail, I consulted the vast wisdom of the internet. And found a lovely recipe, The Bitter Elder in a comment by "Ameture Hour" on a post called Campari: Take 4 at Oh Gosh!.
1.5 ounces gin
.75 St. Germain
.5 fresh lemon juice
I amended this to 1 unit St. Germaine for friendliness, and .75 Campari, because there's no sense being too friendly. The result was astonishingly pleasant, and quite pretty as well.
