Sometimes crazy is good like “Angels Share”, it could also be great. Looking in “Bartenders manual” in Swedish by Mathin Lundgren we found the most strange Manhattan. Combine bourbon with amaro and créme de cassis. Unexpected, yes, but it was quite exciting. You should try everything once, for this there might be a second one.
2 oz bourbon
0,5 oz amaro averna (we used abano)
0,3 oz créme de cassis
Stir with ice and strain
