I tried Jay's suggestion after the original, and I prefered the original. In fact, I like it even better if I used a little rich syrup as well - I know this is pretty sweet and orangey, but I like it! BTW, I used an atomizer to mist absinthe, and didn't do the wash.
Being a real fan of New Orleans and it cuisine, I have drank the traditional Sazerac, but this is wonderful. I did use an 117 proof rye as I was concerned the amount of grand Marnier would be too sweet. Also did a spray of absinthe on the top of the cocktail before serving. It was great for our starting of Mardi Gras.
So happy I tried this! It completely caught me by surprise and though I did make a couple of adjustments to the original recipe (used rye whiskey instead of bourbon and orange bitters instead of Angostura) I think it was a complete success! Will definitely enjoy this again. Many thanks for the recipe?
