I agree with the sentiment that you can make a lovely drink with vodka and vermouth , but it 's no martini . For me , it needs to consist of ice - cold gin , a smidgen of vermouth , perhaps a bit of olive juice , and a big olive skewered on one of various cocktail picks that seem to reproduce nightly in our dining room . Shaken , not stirred , and poured into the glass quickly before any of the ice in the shaker can melt . While I love stories of extra - dry martini rituals , like FDR making his martinis by filling the shaker with gin and then glancing at the vermouth bottle across the room , I am not militant about the exact amount of vermouth to go in the glass .
