It pains me to be disagreeable, but martinis lost their virginity long ago. They are now pretty much anything served cold in a martini glass. The "Lemontini" is/was part of the "...tini" craze that crested a few years ago on the coasts, but is apparently still going strong in the midwest. It's typically served as a "girly" drink, or with dessert.
2 ounces lemon vodka
1/2 oz (good quality) dry vermouth, such as Noilly or Martini
1/2 oz of triple sec, and
Garnish with a lemon drop
Pour the lemon vodka and vermouth into a shaker filled with ice. Let the shaker sit while you put a few cubes in a martini glass, then add the triple sec directly to the glass. Swirl the triple sec and ice cubes in the glass to chill it and coat it with the aromatic liqueur. Discard the ice and triple sec, and put a lemon drop in the bottom of the glass. As the cold glass begins to frost from condensation, pick up your shaker and shake vigorously until it's too cold too hold. Finally, strain the drink into the glass.
Let me know what you think,
