Quite good, but the flavor of the cognac risks getting buried, although the warmth comes through nicely. Think on balance I prefer the Christmas Daiquiri, one of my favorites. (Typo sidenote: "cognac" is currently spelled "coganc" on the default Remy Martin brand.)
I have developed the "Pomopolitan" for Christmas parties - 1-1/2 oz vodka, 1/2 oz fresh lime juice, 2 oz Pom, 1 oz Cointreau, lime wheel garnish, shaken and strained individually if a small group. The batch version is stirred, put in the freezer and includes a small amount of water. (Recipe for 12 servings available).
It's a red and green wonder and can be self served, doesn't require ice, and looks great in your favorite coupe!
I used falernum syrup and cranberry compote liqueur (wijnant focking - amsterdam). I guess it gives a bit more cranberry forward cosmo. Taste is punchy sour and sweet with a decent cognac base (Montifaud VS)
Had this with luncheon on Christmas Eve. Perfect. Great colour, and the cocktail fit perfectly for the Christmas holidays. A great addition to our December holiday cocktails. Thanks again Simon for a wonderful cocktail.
