I would say go easy on the seasoning on the garnish, as it can overwhelm the drink, but really a great cocktail. I've been looking for uses for chile liqueur and this is going in my rotation.
1.5 Elijah Craig Small Batch
.5 Ancho Reyes Chili
.25 Luxardo Maraschino Liqueur
1 dash Angostura
Stirred down like an Old Fashioned, strained onto a large cube.
I hem and haw between a lemon or an orange zest expressed gently onto the drink, both are great, depends on the person which I choose.
