I also went with a 1:1 ratio (used Heaven Hill BiB) and it was quite tasty. I think next time I will go with the recipe and use my Old Grand-Dad 114 as a high-rye and high-proof bourbon to try and stay true to the recipe while accentuating the bourbon

Like a number of the comments here, I, too, find this a little sweet with the 2:1 ratio. I used a 45% ABV bourbon, but I don't think a 100-proof rye would be enough: the ratios might just need to be adjusted. Otherwise, it's a lovely drink.

Made this with Monte Amaro, Kentucky corn whiskey (50° proof), orange bitters, black walnut bitters (this last is an amazing chocolate/not chocolate ingredient). Loved it.
So it's sweet - is that a sin?

Braulio, Crown Royale, angostura orange bitters, one drop chocolate bitters. Very smooth and balanced sipper.

Looks pretty sweet as written so I tried “perfecting” it by replacing half of the Montenegro with dry vermouth di Torino. Used Stranahan’s cask strength Rocky Mountain single malt whiskey. Very good, and still plenty sweet.

I made this with (gulp) Nonino instead of Monte and orange bitters instead of orange peel. I skipped the cherry bc of the Nonino’s inherent sweetness. A delicious variant!

Question. Is there a way to switch back and forth on the ingredients between what you recommend/chose vs "my ingredients" without logging off and back on? For example, I have a variety of Bourbons/Whiskeys that I could have used here but was just curious as to what YOU went with. It seems to pick the same "my ingredient" to sub for your chosen ones.
Thanks

Used a high proof Rye Whiskey to counter a bit more of the Montenegro Amaro's sweetness. It was good. Still a touch sweet, so next time I may do 1.5 oz (45 ml) each of Amaro and Rye.

Kind of sweet- maybe less montenegro?
