  • Used Ransom Old Tom, 1/4 Tempus Fugit creme de cacao and dash Bittermens mole bitters with 3/4 CioCiaro to approximate Meletti, K&L select barrel Elijah Craig for the bourbon.
  • One of the best uses of Fernet I've ever had - where the Fernet is actually complementary / matched. Strong drink, but excellent. I used Ransom's Old Tom and Bulleit. — ★★★★★

Higher math was always a stumbling block, so I was hesitant to try "Silvio's Algorithm." Until I looked at the ingredients, that is! I knew from the beginning that this drink was the Drinker's Drink. And the proof was in the pudding, as it were.

I used Bols Genever Amsterdam gin--barrel-aged as specified, Angel's Envey, a good, but not well known bourbon--this batch distilled in port wine barrels at 86.6 proof, a skinney Fernet Branca, Aperol, and Amaro Meletti. And lemon zest, to finish it off. This is an incredibly smooth drink. The Meletti is there, as is the Aperol. Both provide a slight but necessary bitterness. The Genever gin sits quietly in the background, giving room for the bourbon to speak up, but softly so. And the lemon zest is a necessary must, to round out the flavors.

There is a lot of alcohol in this drink, so plan accordingly. Two of these says get an alternate driver! But this drink is like a potato chip; it's hard to stop with one. So enjoy, but be careful. I rate "Silvio's Algorithim at a well-deserved 5.0.

Used St. George Dry Rye Reposado for fear that an Old Tom might be too sweet.  The result felt a little too astringent.  Would try Genever next time around.
