Ordering a Dry Martini is a lot like ordering a steak. What cut of meat? How well done? And with what sauce? The analogy translates to Martini garnishes...
I just opened my new bottle of Vermouth, a Chazalettes. Turned out almost wine-like, very little vermouth in that vermouth. So I guess this discussion about ratios completely depends on which vermouth you choose. Unfortunately Dolin is not available here.
