This was delicious, but even as someone who is a fan fernet, a 1:1 is a bit much. I only did 1/4oz simple syrup as well, but that was preference. 1/2oz seemed like it would have been fine too.

For the next mix, I'll probably do a 2:1 bourbon to fernet or higher to allow the bourbon a little more room to shine. All that said, very tasty after dinner cocktail.
