Used what I had and it turned out surprisingly better than expected, but the vermouth seriously just sticks out like a sore thumb. Subs: Willett 4 Year Rye (112.2 proof), Four Roses bourbon, Cinzano Extra Dry vermouth.
A whisky-heavy Boulevardier with a dash of chocolate. It doesn’t work for me, partly because the Martini gets swamped by the other flavours. Certainly not unpleasant, but not great either.
