2 1/12 fl oz  Hayman's London Dry Gin
5/12 fl oz  Strucchi Dry Vermouth

Review: This is my go-to Dry Martini, although I arrive at the same 5:1 ratio with a generous 75ml (2½oz) gin to 15ml (½oz) dry vermouth. I chose a 5:1 ratio as our 'preferred' Dry Martini specification in deference to David Embury who writes of this drink in his The Fine Art of Mixing Drinks "After extensive experimentation I have arrived at the ratio of 5 to 1 as the proportion most pleasing to the average palate. Personally I like a ratio of about 7 to 1 even better, and I know some who prefer a ratio as high as 10 to 1."

The proportion of gin to vermouth is a matter of taste; some say 5 to 1, others that one drop is sufficient. I recommend you ask the drinker how they would like their Martini, in the same manner, that you might ask how they have their steak.

Variant: The 'Oliver Twist' choice between an olive (stuffed or otherwise) or a lemon zest twist is traditional and these are the two most common garnishes for a Dry Martini. There are, however, a number of variants.
