Gin Martini:
Pour 1/2 ounce of vermouth into glass, swirl around so that vermouth lines glass, pour out excess.
Pour 2 1/2 ounces of gin (tanqueray, bombay saphire, plymouths) into your ice filled jig. Shake vigorously.
Pour gin into glass with strainer on. Garnish with olive or lemon twist (optional.)
Martini's are the dressy way to drink straight booze. The old saying goes: one martini is plenty, two is too much, three is not enough.
I can look into my old martini book and post up other recepies tomorrow.
