Mon Nouvel Ami is David Lebovitz's variation on the Old Pal Cocktail, substituting Dolin red for Campari. Lebovitz published his recipe in his Drinking French book. The result was a less bitter drink. My wife described the Dolin as more botanical in flavor.
Largely because of the Lebovitz recipe, I've had my eye out for Dolin for a while. Technically, it's a vermouth, though more flavorful - and more expensive - than the usual offerings. It's not available in Vermont liquor stores so I always keep an eye out for it when we're out of state. Wouldn't you know, I'd find a gem of a liquor store in Northampton, Massachusetts: State Street Wine, Beer & Spirits. I was able to cross off a decent portion of my wish list so stay tuned.
