Jian and I just tried this cocktail recipe at home, but with a few minor substitutions. We recently ran out of Redbreast Irish Whiskey & Laphroaig 10-year Scotch. In our house, we tend to go through many bottles of whisky, whiskey, & bourbon within a relatively short amount of time…but that doesn’t mean we don’t savor or enjoy our bottles. Of course we thoroughly enjoy every single drop of each delightful brown liquor. To put things plainly: We. Drink. A. Lot.

Anyway, we were missing 2 out of the 5 ingredients for this recipe. We substituted the Irish whiskey for Gentleman’s Jack whiskey & substituted Laphroaig Scotch with Lagavulin 16-year Scotch. Ever since I introduced Jian to St. Germain Elderflower liqueur, we always keep a bottle stocked in our kitchen, so there was no substitution there. However, instead of using Death & Co.’s brand of bitters, we used a mix of Fee Brothers Orange BittersAngostura Bitters. With a twist of the lemon rind…& voilà! We made our own version of the Cooper Union cocktail, & it was deee-lish! Cheers!
