Fantastic drink, although I prefer the balance of the Death & Co. version:

1 1/2 oz rye
1/2 oz dry vermouth
1/2 oz blanc vermouth
1/2 oz lemon juice
1/2 oz grenadine
1x dash orange bitters
lemon twist, discarded

I used homemade grenadine (Morganthaller recipe with a little rose water added), Rittenhouse, Dolin dry, Carpano bianco, Reagans' orange bitters

I'll have to try the lime version next.

Great cocktail! I used Appleton Signature, and I may try upping it to 1 1/3 oz next time.

This, the Bird of Paradise, and the Pink Squirrel inspired me to create something a little less sweet and a shade smokier, which I'm currently calling the Mexican Fox Squirrel: 1 1/4 oz Montelobos Espadin Mezcal, 1/2 oz Tempus Fugit creme de cacao, 1/2 oz Tempus Fugit creme de noyaux, 1 1/2 oz cream (I used Country Crock non-dairy whipping cream, but regular whipping cream is fine, too). Shaken with a ground nutmeg garnish.

Used Ardbeg Wee Beastie, Meletti, and Dolin Rouge. Amazingly, it all works. Can't tell if an orange peel would be a nice add or somehow break the delicate balance.
