I like both spirit-forward cocktails and gin, so although the original recipe calls for equal parts gin and dry vermouth, I previously opted for two-parts...
I enjoyed the sweetness and vermouth back-end of this drink. I used Barr Hill as my gin, which has honey added and close to an old Tom. Benedictine seems to bridge the vermouth and gin nicely and compliments the aroma of the bitters and zest. This drink is sweet and pair with that in mind.
