Ok, let's take a breath. On the one hand, kudos to anyone for having an opinion. On the other hand, opinions can be changed. And the right cocktail - regardless of your spirits preference - can be eye-opening, life-affirming, and opinion-swaying.
In fact, about a month ago, I converted a Gin-hating friend by serving her a Gin Sour made with Barr Hill Gin, a gentle spirit flavored with honey. Purists (who insist, with good reason, that true Gin is juniper-forward) wouldn't call it Gin, but then it ain't Whiskey either.
My point here is that opinions are based on experience, and the way to change them is to provide a better experience.
French 75: Gin's "gateway" drink
If you think this sounds suspiciously like a Gin sour - Gin, sugar, citrus - you'd be right. But nothing makes a spirit go down - and be lifted - like a dose of fizz.
For those of you who already accept Gin as "the" spirit, good on you. For those of you who don't - or for your friends who are misguided naysayers - mix up some French 75s and say "oui, oui" to Gin.
And, if you refuse to embrace the juniper spirit, you are forgiven. Simply sub Cognac or Brandy and you'll have yourself a French 125.
