1 oz Plymouth gin
1/4 oz Matilde Peche liqueur
1/4 oz Cocchi Americano
1/4 oz dry vermouth
2 dashes orange bitters (I think Fee's was used originally)
Rinse a coupe with absinthe and place in the freezer to chill (or "season", as they say with Sazeracs). Stir the above over rocks and then strain into the coupe, then twist a strip of orange peel over the top and whirl it into a tight circle resembling a flower; perch this on the rim as garnish.
Now, that's a damned fine beverage, no doubt about it. After sampling one after work, I got home and wondered if I could try something similar with Matilde Poire, which had been hanging out in my cabinet for some time. Gin didn't seem quite right, so I switched to rye, which was just way too assertive. So I did something that I thought a little crazy and tried scotch instead. A couple minor adjustments later and we have the beverage below:
1 oz blended scotch (use a single malt if you like, just something mild - you don't want too much peat here)
1/4 oz Matilde Poire liqueur
1/4 oz Cocchi Americano
1/4 oz sweet vermouth (Punt e Mes is also nice)
2 dashes Regan's No. 6 orange bitters
Rinse a coupe with absinthe, etc etc. Do the same fanciness with the orange peel, if you like, or just squeeze an orange coin over the top and drop in.
(Being something of a lush, I actually find that the above is a rather small drink for my tastes. If you think the same, double all of the proportions and use a classic martini glass instead.)
This to me is proof that experimentation and substitution can be the origin of many a fine cocktail. That is after all how we got from Manhattans to Martinis, and from Sidecars to Margaritas.
