I’m going to try this again, and tweak it because I really liked it, but think I can do better. Unlike the review above, I found it too sweet, so added a touch more vinegar. It probably also depends on how ripe your tomatoes are. I also added Scrappy’s Fire Tincture which matched well and complemented the pepper. Next time I’ll cut back on the simple syrup, and carefully watch the balance.
Fernet Branca can be a bit much to me, as I have a genetic sensitivity to bitterness - but I found this very enjoyable. Used Russell’s Reserve 90 proof.
