Lately, having a forethoughtless moment hereabouts, I realized I was without any species of vermouth. The situation threatened to crimp my daily martini intake, which is the ethnically-prescribed one on arriving home from work.

Happily, I have found that a decent midrange sake does the job, and frankly, even improves upon the original.

1 oz sake
2 oz gin

Shake over cubes until you fear frostbite in your extremities. Decant over one, preferably Goya, pimento-stuffed green olive.
