I'm all evens on my Negroni-style drinks 1 to 1 to 1.
1.75oz rye -I used High West.
1.75oz citrus bitter -Most recipes call for Campari, I used Luxardo Bitter here.
1.75oz Byrrh
2 dashes Boston Bittahs -Using orange bitter is also acceptable.
Build the drink in a rocks glass. Garnish with a flamed orange peel if you're feeling fancy.
