There are a lot of new American gins worth exploring, and some wonderful things to mix them with (such as Crème Yvette, returned after many decades).
In fact, I think I'll go have a Blue Moon cocktail right now...
2 ounces gin
1/2 ounces freshly squeezed lemon juice
1/2 ounce Crème Yvette
Shake in iced cocktail shaker, and strain into a small cocktail glass. Garnish with a lemon twist.
