2 oz Rye, Old Overholt
1 1⁄3 oz Sweet vermouth, Martini & Rossi
1 bsp Amer Picon
1 bsp Triple sec, Cointreau
1 cube Sugar
Muddle bitters and sugar, add remaining ingredients, add ice, stir and strain into a chilled coupe glass. Lemon peel garnish
I adapted this from a 1935 Reprint of Bar Florida Cocktails. Original called for (based on book) 1/3 Rye, 1/2 M&R Vermouth (dry or sweet?), 1 tsp Amer Picon, 1/2 tsp curacao, 1/2 tsp sugar, dash bitters and lemon peel. I'm assuming measurments are ounces so it seemed like a small drink to me.....
I really dislike ratios, but they're common in a lot of books from the 30's. If you're going to set your volume = 4, 1/2 is 2 and 1/3 is 4/3, so the recipe should be 1 1/3 oz M&R, and a barspoon of Amer Picon. I can change this if you'd like.
